Mark the center hole and drill carefully using a step bit — go slow to avoid cracking the windshield (polycarbonate or glass). Install the mounting bolt with the rubber washers on both sides to create a watertight seal. Adjust the wiper arm angle and blade orientation for maximum sweep coverage. Test the full range of motion before final tightening. Frequently Asked Questions Q: Will this fit my curved windshield? A: This wiper is designed for flat windshields. On curved or contoured windshields, the blade may not make full contact across the entire sweep. For best results, verify your windshield is flat or gently curved before ordering. Q: Can I install this on a polycarbonate (Lexan) windshield? A: Yes. Use a step drill bit and go slowly to prevent cracking. The included rubber gaskets create a watertight seal that won't damage polycarbonate. Q: How long does the wiper blade last? A: With normal use the rubber blade insert should last 1-2 seasons. The blade is a standard 15.7" (400mm) replaceable insert available at most auto parts stores. Q: Can I install this on the passenger side too? A: Yes — two wipers can be installed for full windshield coverage. One kit covers one side. Order two for dual-wiper setup. Q: Does this work in freezing conditions? A: The manual lever operates regardless of temperature. However, frozen rubber blades on icy windshields should be freed before operation to prevent tearing the blade insert. Q: What's the mounting hole size? A: The mounting bolt requires a 3/8" (10mm) hole through the windshield. The included grommets and rubber washers accommodate windshield thickness from 3/16" to 1/2". 🔗 Related Products from iFJF Bluetooth Battery Kill Switch for UTV UTV Windshield Mounting Clips Straps 📚 Helpful Installation Guides 📖 SPELAB 4" Straight Pipe Kit Install

Compatibility Vehicle Year Range Engine Notes Suzuki King Quad LT4WD 1991-2002 250cc 4-stroke All sub-models (LT-4WD, LT-F4WD) Suzuki Quad Runner LT-250 1988-1999 250cc 4-stroke LT-250F, LT-250EF Suzuki LT-250F Various 250cc 4-stroke Verify pump style on early models Cross-Reference / Interchange Brand Part Number Suzuki OEM 15100-19B01, 15100-19B00 Signs Your ATV Fuel Pump Needs Rebuilding Hard starting after sitting: Fuel drains back to the tank — excessive cranking required to prime the carburetor. Engine dies under load: Fuel pump can't maintain adequate volume when climbing hills or at wide-open throttle. Surging at speed: Intermittent fuel delivery causes RPM fluctuations. Fuel smell from vacuum line: Perforated diaphragm allows fuel into the engine vacuum circuit. Visible diaphragm damage: Upon disassembly, the rubber diaphragm is stiff, cracked, or has pinholes. Frequently Asked Questions Q: Does this fit all Suzuki King Quad models?A: This kit fits the 250cc King Quad LT4WD and Quad Runner LT-250 models with the vacuum-operated pulse fuel pump. Not compatible with the King Quad 300, 400, 500, 700, or 750 models which use different fuel delivery systems. Q: How do I know if the fuel pump is my problem?A: A quick test: disconnect the fuel line at the carburetor, place it in a container, and crank the engine. Fuel should pulse out steadily. If flow is weak, intermittent, or absent, the pump diaphragm is likely the culprit. Also check the vacuum line for fuel — if fuel is present in the pulse line, the diaphragm is definitely perforated. Q: Can I rebuild it on the ATV?A: The pump is typically mounted on the frame or engine with 2-3 bolts. Remove it for easier access. Rebuilding on a bench allows proper cleaning of mating surfaces and inspection of the pulse port for obstructions. Q: How long will the rebuilt pump last?A: With ethanol-free fuel, 5-8+ years. With E10 pump gas, 3-5 years. For longest life, drain the carburetor and run the engine dry before winter storage to prevent fuel varnish buildup in the pump. Q: What if the rebuild doesn't fix my fuel delivery issue?A: Check the vacuum pulse line for cracks or blockages, verify the fuel tank vent is clear (a blocked vent creates vacuum lock), and inspect fuel lines for kinks or internal collapse. If the pulse port on the engine is clogged with carbon, clean it out. Related Blog Posts Marine Fuel Water Separator Guide Cummins Onan RV Generator Fuel Pump & Filter Guide

A clogged or dirty air filter is one of the most overlooked maintenance items on diesel trucks — yet it directly impacts engine performance, fuel economy, and turbocharger life. The 5.0L Cummins in the Titan XD relies on precise air-fuel ratios for clean combustion. A restricted air filter forces the turbo to work harder, increases EGTs (exhaust gas temperatures), and can trigger DPF regeneration cycles more frequently. Replacing your air filter at regular intervals is one of the cheapest ways to protect your investment. Signs your air filter needs replacement: Decreased fuel economy (2-5% drop is common with a dirty filter) Reduced throttle response or sluggish acceleration Black smoke from exhaust (incomplete combustion) Visible dirt or discoloration on filter media Check engine light (MAF sensor contamination) Filter exceeds 30,000 miles since last replacement Installation Overview Replacing the air filter on the 2016-2020 Nissan Titan XD 5.0L Cummins is a simple DIY job requiring no tools in most cases: Park on level ground, engine off and cool Locate the air filter housing on the passenger side of the engine bay Unclip the 4 metal spring clips securing the air box lid Lift the lid and remove the old filter Inspect the housing for debris — wipe clean if needed Insert the new iFJF 16546-EZ40A filter with the rubber seal facing down Re-secure the lid and ensure all clips are fully engaged Reset the air filter minder if equipped Estimated time: 5-10 minutes | Difficulty: Beginner Frequently Asked Questions Q: Will this fit my 2018 Nissan Titan XD with the gas 5.6L engine?A: No. This filter is specifically designed for the 5.0L V8 Cummins diesel engine. The 5.6L gasoline V8 uses a different air box and filter element. Please verify you have the diesel engine before ordering. Q: How often should I replace this air filter?A: Nissan recommends inspection every 15,000 miles and replacement every 30,000 miles under normal conditions. If you frequently tow heavy loads, drive on gravel/dirt roads, or operate in dusty environments (construction sites, farming, desert regions), replace every 15,000 miles or sooner. Q: Is this a washable/reusable filter?A: No. This is a standard dry paper-element filter designed for one-time use and replacement. Do not attempt to wash or oil this filter — doing so will damage the filtration media and may cause engine damage. Q: Will a dirty air filter cause my check engine light to come on?A: Potentially yes. An excessively clogged filter can cause MAF (Mass Air Flow) sensor readings to go out of range, which may trigger a check engine light. If you have a P0101 or related MAF code, check your air filter first before replacing sensors. Q: Does this filter affect my DPF (Diesel Particulate Filter)?A: Indirectly, yes. A restricted air filter causes incomplete combustion, which produces more soot — accelerating DPF loading and triggering more frequent regeneration cycles. Keeping a clean air filter helps your emissions system operate as designed.

Carburetor Repair Kit for Johnson/Evinrude V4 & V6 Crossflow Outboards The iFJF 18-7046 carburetor repair kit is specifically engineered for the V4 (85, 90, 100, 115, 140 HP) and V6 crossflow Johnson and Evinrude outboard engines. These legendary 2-stroke powerheads rely on precision carburetion for their signature performance — and this kit provides everything needed to restore each carburetor to factory specifications. Replaces OEM 439076 and covers V4 Crossflow and V6 Crossflow carbureted models. Key Features V4/V6 Crossflow Specific: Engineered for the high-performance carburetor design used on Johnson/Evinrude 85-140HP V4 and 150-235HP V6 crossflow engines. Complete Rebuild Kit: Float bowl gasket, inlet needle & seat, all body gaskets, mixture screw o-ring, welch plugs, and drain screw washers. High-Performance Fuel Systems: Precision needle & seat ensures consistent fuel level control at the high fuel flow rates demanded by V4 and V6 carburetors at WOT. Ethanol-Ready: Upgraded materials resist the ethanol-related degradation that plagues original 1980s-1990s rubber components. Restores Peak Power: Fixes lean conditions, fuel starvation, and uneven cylinder-to-cylinder fuel distribution that robs horsepower. Compatibility Engine Family HP Range Configuration Carb Count V4 Crossflow 85, 90, 100, 115, 140 HP V4 2-stroke 2 carburetors V6 Crossflow 150, 175, 200, 225, 235 HP V6 2-stroke 3 carburetors Cross-Reference / Interchange Brand Part Number Johnson / Evinrude OEM 439076 Sierra Marine 18-7046 GLM Marine 40570 Mallory Marine 9-37100 Installation Considerations for Crossflow Engines Carb synchronization is critical: After rebuilding all carburetors, adjust the throttle linkage so all throttle plates open simultaneously. Uneven opening causes cylinder-to-cylinder fuel imbalance. Check reed valves: While carbs are off, inspect the reed valves for chipping or fatigue. Damaged reeds cause spit-back and poor low-speed running. Verify timing: After carb rebuild, verify WOT timing with a timing light. Lean conditions from vacuum leaks can cause detonation at high RPM. Link and sync procedure: Follow the factory "link and sync" procedure for your specific model to set idle timing, pickup timing, and WOT timing correctly. Frequently Asked Questions Q: Will this fit my 1985 Johnson 115 HP V4?A: Yes, if your 115HP V4 uses the crossflow carburetor design (most 1980s models do). Verify your carburetor's OEM part number is 439076 or the equivalent crossflow carb series. Q: How many kits do I need for my V6 200 HP?A: V6 crossflow engines use 3 carburetors — you'll need 3 kits for a complete rebuild. Always rebuild all carburetors simultaneously for balanced performance. Q: Does this kit work for looper engines?A: No. This kit is for crossflow (deflector piston) engines only. Looper engines (60-degree V4 and V6 loop-charged models) use different carburetors. Verify your engine type before ordering. Q: What's the most common mistake during V4/V6 carb rebuild?A: Failing to properly synchronize the carburetors after installation. Even with perfectly rebuilt carbs, uneven throttle plate opening creates cylinder-to-cylinder imbalance. Always perform a link & sync procedure after rebuild. Q: My engine bogs when I hammer the throttle — will this fix it?A: Possibly. Bogging on acceleration is often caused by clogged high-speed jets or a failing accelerator pump circuit. The thorough cleaning during rebuild combined with new components addresses these issues. If bogging persists, check the accelerator pump diaphragm separately.

Common Fixes: Resolves fuel drip from carb throat, rough idle, bogging on acceleration, and hard hot re-starts. Cross-Reference Interchange Brand Part Number Sierra Marine 18-7226 Mercury / Mariner OEM 35-16494-1, 35-816296-T1, 35-816296-1, 35-816296Q2, 35-816296T1 OMC / Johnson Evinrude 398327 Mallory Marine 9-37404 Technical Specifications Application: Mercury / Mariner 2-stroke outboard carburetors Carburetor Type: Float bowl design (side bowl or center bowl applications) Kit Contents: Float bowl gasket, inlet needle & seat, body-to-adapter gasket, mixture screw o-ring, welch plugs, drain screw gasket Material: Ethanol-resistant Buna-N / Nitrile rubber, composite gasket material Fitment Type: Direct replacement Why Rebuild Instead of Replace? A complete carburetor assembly for a 2-stroke outboard can cost $200-400+. In most cases, the aluminum carburetor body itself is perfectly serviceable — only the soft components (gaskets, seals, needle valve) have degraded. The iFJF 18-7226 rebuild kit costs a fraction of a replacement carburetor and, when installed correctly, restores like-new performance. This is especially cost-effective for older engines where OEM carburetors may be discontinued or backordered. Installation Guide Remove carburetor: Disconnect fuel line, throttle linkage, and choke linkage. Remove mounting bolts/nuts. Disassemble completely: Remove float bowl, float pin, float, inlet needle, and all gaskets. Note the order of disassembly. Clean thoroughly: Soak all metal parts in carburetor cleaner. Use compressed air to blow through every passage and jet. Verify jets are clear. Install new components: Replace all old gaskets and seals with new kit components. Install new inlet needle & seat. Set float height: Verify float level matches specification. Adjust tab if needed. Reassemble and test: Reinstall carburetor, connect linkages and fuel line. Prime bulb, check for leaks before starting. Frequently Asked Questions Q: How do I confirm this kit fits my outboard?A: This kit is designed for Mercury/Mariner 2-stroke carburetors using OEM part numbers 35-16494-1 or 35-816296 series. Check the model number stamped on your carburetor body, or search your engine's serial number against the Sierra 18-7226 fitment guide. Contact us with your engine details if unsure. Q: Does this kit include a new float?A: No. The float is a separate component that typically only needs replacement if cracked or fuel-saturated. If your float is damaged, you'll need to source it separately. A simple test: shake the float — if you hear liquid inside, it needs replacement. Q: How many carburetors does one kit service?A: One kit services ONE carburetor. If your outboard has 2, 3, or 4 carburetors, you'll need multiple kits. We recommend rebuilding all carburetors simultaneously for balanced performance. Q: Will this fix my motor dying at idle?A: Possibly. Dying at idle is often caused by a clogged pilot/idle circuit or vacuum leak from a deteriorated gasket. A thorough cleaning during the rebuild combined with new gaskets resolves this in most cases. If the issue persists after rebuild, check for vacuum leaks at the intake manifold or crankshaft seals. Q: Can I use this kit with a carburetor that has been sitting with old fuel for years?A: Yes — and this is one of the most common use cases. Carburetors that have sat with ethanol fuel often have completely varnished internals. Follow the cleaning steps carefully, and consider an ultrasonic cleaning if the varnish is heavy. The new kit components will restore the sealing surfaces after cleaning.

Compatibility Engine Carburetor Application Mercruiser 3.0L (181 ci) 2-Barrel Mercarb Sterndrive, 4-cylinder, various years Mercruiser 3.0LX 2-Barrel Mercarb Sterndrive, 4-cylinder Mercruiser 3.0L MPI (Verify) N/A — Fuel Injected ❌ Not Compatible — MPI models don't use carburetors Cross-Reference Brand Part Number Sierra Marine 18-7665 Mercruiser OEM 70125A-1 Signs of a Failing Electric Choke Hard cold starting: Choke doesn't close fully — engine cranks excessively before firing. Engine stalls when cold: Choke opens too quickly, leaning out the mixture before the engine is warm. Black smoke / rich running when warm: Choke stays partially closed — heating element has failed. Rough idle after cold start: Choke opening inconsistently due to intermittent electrical connection. High idle persists too long: Heating element weak — choke takes excessive time to fully open. Installation Overview Disconnect battery negative terminal (safety first in marine environments). Remove the flame arrestor / air cleaner assembly. Disconnect the old choke electrical connector. Remove the old choke assembly (typically 2-3 screws on the carburetor housing). Install the new iFJF 18-7665 choke, ensuring the choke plate linkage engages correctly. Connect the electrical lead to 12V ignition-switched power. Verify choke operation: cold engine → choke plate should be nearly closed. Apply 12V → plate should slowly open over 2-5 minutes. Frequently Asked Questions Q: Does this fit all Mercruiser 3.0L engines?A: This choke fits Mercruiser 3.0L engines with the 2-barrel Mercarb carburetor. It does NOT fit 3.0L MPI (multi-port fuel injection) models, which don't use a carburetor or choke. Verify your engine has a carburetor before ordering. Q: How do I test my existing choke?A: With a cold engine, remove the flame arrestor. The choke plate should be nearly closed. Start the engine and observe — the plate should slowly open over 2-5 minutes. If it stays closed after 5+ minutes, the heating element is dead. If it snaps open immediately, the bimetal spring is broken. Q: Does this require 12V constant or switched power?A: Connect to ignition-switched 12V (only powered when the key is ON). Connecting to constant 12V will keep the choke heating element energized and drain your battery. Q: Can I adjust the choke opening speed?A: The opening speed is determined by the heating element and bimetal spring — not user-adjustable. However, you can adjust the initial choke plate gap via the choke housing rotation. Mark the original position before removal. Q: Is the gasket included?A: If the kit includes a mounting gasket, it will be in the package. If your original gasket is in good condition, it can be reused.

Complete Carburetor Rebuild Kit — Mercury/Mariner Outboard The iFJF 18-7750-1 carburetor repair kit provides a comprehensive solution for rebuilding your outboard carburetor. Engineered for Mercury, Mariner, and compatible 2-stroke outboard applications, this kit replaces all critical wear components — restoring proper fuel metering, eliminating fuel leaks, and returning your engine to peak running condition. Key Features Complete Rebuild Kit: Includes float bowl gasket, inlet needle & seat, body gaskets, o-rings, welch plugs, and drain screw washers — everything required for a full carburetor overhaul. Ethanol-Resistant Components: All rubber and composite parts are formulated to withstand E10 and ethanol-blended fuels that can swell and degrade standard materials. OEM-Spec Precision: Manufactured to exact factory tolerances for proper float height control, leak-free sealing, and consistent fuel delivery throughout the RPM range. Restores Performance: Fixes common outboard issues: hard starting, rough idle, hesitation on acceleration, fuel leaks, and rich/lean running conditions. Cost-Effective: A fraction of the cost of a complete carburetor replacement — and in most cases, the only parts that actually wear out. Cross-Reference / Interchange Part Numbers Brand Part Number Sierra Marine 18-7750-1 Mercury / Mariner OEM 1395-8236354, 1395-8236353, 1395-8236352, 1395-8236351 Why Carburetor Gaskets Fail Modern pump gasoline contains up to 10% ethanol (E10) — a solvent that attacks traditional rubber and cork gasket materials. Over time, ethanol causes gaskets to swell, shrink, or disintegrate entirely. This kit's components use upgraded materials designed to resist ethanol degradation, providing a longer-lasting seal in today's fuel environment. For maximum lifespan, we recommend using ethanol-free marine fuel whenever available. Installation Tips Document everything: Take photos of linkage positions, hose routing, and gasket orientation before disassembly. Deep clean: Soak the stripped carburetor body in quality carb cleaner. Blow compressed air through every passage. Verify float height: Check and adjust to factory specification before closing the bowl. Incorrect float height is the #1 cause of post-rebuild running issues. Replace one at a time: On multi-carb engines, rebuild carbs individually to avoid mixing up components. Primer bulb test: After reassembly, pump the primer bulb until firm and check for leaks before starting. Initial start: It may take several pulls or extended cranking to fill the dry carburetor with fuel. Frequently Asked Questions Q: How many carburetors does one kit cover?A: One kit services ONE carburetor. If your outboard has 2, 3, or 4 carburetors, order the corresponding number of kits. For best results, rebuild all carburetors at the same time for balanced fuel delivery. Q: Does this kit include new jets?A: No. Jets are typically reusable unless physically damaged or severely corroded. The jets in your existing carburetor can be cleaned and reinstalled. If you need replacement jets, they're available separately. Q: Will this fix my engine running rough at low RPM?A: In many cases, yes. Rough low-speed running is often caused by a clogged pilot/idle circuit or air leak from deteriorated gaskets. The thorough cleaning you'll perform during the rebuild, combined with new gaskets, addresses both issues. Q: How long does a rebuilt carburetor last?A: With ethanol-free fuel, 5-10+ years before another rebuild is needed. With E10 fuel and regular use, expect 3-5 years. Running the carburetor dry before storage significantly extends rebuild life by preventing fuel varnish buildup. Q: Can a beginner rebuild an outboard carburetor?A: Yes, with patience and organization. Key requirements: a clean workspace, good lighting, a service manual for your specific engine, and the discipline to not rush. Budget 1.5-2 hours per carburetor.

Restores Performance: Fixes common symptoms like hard starting, rough idle, bogging on acceleration, and fuel leaks from bowl gasket deterioration. Compatibility Engine HP Range Notes Mercury / Mariner 2-Stroke 40HP, 45HP, 50HP Late 1980s-1990s models (verify carb model) Tohatsu 2-Stroke 40HP, 50HP OEM equivalent fitment Yamaha 2-Stroke 40HP, 50HP Select models — verify carburetor type Cross-Reference Part Numbers Brand Part Number Sierra Marine 18-7768 Mallory Marine 9-37503 Yamaha OEM 6H4-W0093-03-00, 6H4-W0093-02-00 GLM Marine 40310 When to Rebuild Your Carburetor 2-stroke outboard carburetors are precision instruments that meter fuel based on airflow. Over time, the rubber gaskets, o-rings, and float needle seats degrade — especially when exposed to ethanol-blended fuels. A rebuild kit like the iFJF 18-7768 restores factory-spec fuel delivery without the cost of a complete carburetor replacement. Common symptoms indicating a carburetor rebuild is needed: Engine cranks but won't start (fuel not reaching cylinders) Rough or surging idle (vacuum leak from dried gaskets) Bogging or hesitation on acceleration (clogged jets or worn accelerator pump) Fuel leaking from carburetor body (failed float bowl gasket) Engine runs only with choke partially engaged Excessive fuel consumption or fouled spark plugs Installation Tips Work clean: Disassemble on a clean white towel to catch small parts. Photograph each step for reference. Soak and clean: Use carburetor cleaner to soak the disassembled body and jets. Blow compressed air through all passages. Replace in order: Follow the gasket sequence — float bowl gasket last so the float height stays correct during assembly. Check float height: Verify float level specification before closing the bowl. Incorrect float height = rich or lean condition. Prime before starting: Squeeze the primer bulb until firm before cranking. It may take several pulls to fill the rebuilt carb with fuel. Synchronize if twin: On dual-carb applications, adjust linkage so both throttle plates open simultaneously. Frequently Asked Questions Q: Does this kit fit my specific 50HP Mercury outboard?A: This kit fits 40-50HP Mercury/Mariner 2-stroke outboards from the late 1980s through 1990s. To confirm, check your carburetor model number (stamped on the carb body) or verify your engine serial number against the Sierra 18-7768 application guide. Contact us with your serial number if uncertain. Q: What's included in the kit?A: Complete set includes: float bowl gasket, inlet needle & seat assembly, mixture screw o-ring, welch/expansion plugs, bowl drain screw gasket, fuel inlet gasket, and all body-to-manifold gaskets. Everything needed for one carburetor. Q: Can I use this kit if I run E10 (10% ethanol) fuel?A: Yes. The gaskets and seals in this kit are formulated to resist ethanol-related deterioration. However, we still recommend using ethanol-free marine fuel when available, as ethanol attracts moisture and accelerates corrosion in marine environments. Q: How difficult is a carburetor rebuild for a DIYer?A: Moderate difficulty. If you can change a water pump impeller or lower unit oil, you can rebuild a 2-stroke carburetor. The key is cleanliness and organization. Budget 1-2 hours for your first rebuild. Watch a model-specific video tutorial before starting. Q: Do I need any special tools?A: Basic metric socket set, flathead and Phillips screwdrivers, needle-nose pliers, carburetor cleaner spray, and compressed air are sufficient. A carburetor jet cleaning tool set is helpful but not required.

Fuel Pump Diaphragm & Washer Kit for Mercury/Mariner Outboard The iFJF 18-7817 fuel pump rebuild kit restores proper fuel delivery for your Mercury or Mariner outboard engine. This kit replaces the critical diaphragm and check valves inside the mechanical pulse-style fuel pump — the components most prone to wear and ethanol-related deterioration. Replaces Mercury OEM 21-857005A1 and Sierra Marine 18-7817. Key Features Complete Rebuild Kit: Includes fuel pump diaphragm, check valves, gaskets, and washers — everything needed to restore a mechanical pulse fuel pump. Ethanol-Ready Diaphragm: Upgraded elastomer material resists stiffening, cracking, and perforation caused by ethanol-blended fuels. Restores Fuel Pressure: Fixes weak fuel delivery, hard starting after sitting, and engine stalling under load caused by a failing diaphragm. Direct OEM Replacement: Manufactured to match Mercury/Mariner OEM specifications for pulse pump dimensions and flow rates. Cost-Saving Alternative: A complete OEM fuel pump assembly costs $80-150+. This rebuild kit achieves the same result at a fraction of the cost. Cross-Reference / Interchange Brand Part Number Sierra Marine 18-7817 Mercury / Mariner OEM 21-857005A1 Signs of a Failing Fuel Pump Diaphragm Hard starting after sitting: Fuel drains back to the tank overnight — requires excessive cranking to re-prime. Engine stalls under load: Pump can't maintain fuel volume at higher RPM/load demands. Fuel in the pulse line: A perforated diaphragm allows fuel to enter the crankcase pulse line (dangerous — can dilute engine oil). Surging at cruise speed: Inconsistent fuel pressure causes RPM fluctuations. Visible cracking on diaphragm: Upon inspection, the rubber is stiff, cracked, or has pinholes. Frequently Asked Questions Q: Does this kit fit all Mercury/Mariner outboards?A: This kit is designed for mechanical pulse-style fuel pumps found on many Mercury/Mariner 2-stroke outboards. Verify your pump matches OEM number 21-857005A1 before ordering. Not compatible with electric fuel pump systems. Q: Can I rebuild the pump without removing it from the engine?A: It's possible but not recommended. The pump is typically held by 2 bolts and the fuel lines. Removing it allows you to clean the mating surfaces properly and inspect the pulse port for blockages. Q: What tools are needed?A: Basic hand tools — Phillips screwdriver, flathead for prying, and a socket or wrench for the mounting bolts (typically 10mm or 3/8"). A pick tool helps remove old gasket material. Q: How often should I rebuild the fuel pump?A: As preventative maintenance, every 3-5 years if using ethanol fuel, or when symptoms of failure appear. If you run ethanol-free marine fuel, the diaphragm can last 8-10+ years. Q: Is this kit compatible with fuel-injected outboards?A: No. Fuel-injected outboards use high-pressure electric pumps. This kit is only for mechanical pulse pumps on carbureted 2-stroke engines.

1R-0750 Fuel Filter Refit Head Bolt — Stainless Steel — 2001-2016 Duramax 6.6L The 1R-0750 Fuel Filter Refit Head Bolt is a precision-engineered stainless steel replacement for the mounting bolt that secures the billet aluminum fuel filter head assembly to the engine bracket on 2001-2016 Duramax 6.6L diesel engines. The factory bolt is prone to corrosion and seizing — especially in salt-belt states — making future filter changes a nightmare. This stainless steel upgrade eliminates that problem permanently. Key Features 304 Stainless Steel: Complete corrosion resistance — no rust, no seizing, no snapped bolts during filter service. Unlike the factory carbon steel bolt that rusts solid after a few winters. Precision-Threaded: Exact thread pitch and diameter match the 1R-0750 filter head mounting boss — threads in smoothly without cross-threading. Hex Head Design: Standard socket size for easy removal with common tools — no special bits required. Direct Replacement: One-for-one swap with the original bolt. Remove the old rusty bolt, thread this one in, torque to spec — done in 5 minutes. Anti-Seize Pre-Applied: Factory-coated with nickel-based anti-seize compound for immediate installation and future serviceability. Compatibility Year Make Model Engine 2001-2004 Chevrolet/GMC Silverado/Sierra 2500HD/3500HD 6.6L LB7 2004.5-2005 Chevrolet/GMC Silverado/Sierra 2500HD/3500HD 6.6L LLY 2006-2007 Chevrolet/GMC Silverado/Sierra 2500HD/3500HD 6.6L LBZ 2007.5-2010 Chevrolet/GMC Silverado/Sierra 2500HD/3500HD 6.6L LMM 2011-2016 Chevrolet/GMC Silverado/Sierra 2500HD/3500HD 6.6L LML Frequently Asked Questions Q: My factory bolt is completely seized — what should I do?A: Apply penetrating oil (Kroil or PB Blaster) and let it soak for 30+ minutes. Use a 6-point socket (not 12-point) to avoid rounding. If still stuck, apply heat with a propane torch to the surrounding bracket (not the bolt itself). The thermal expansion will help break the rust bond. Once removed, install this stainless bolt and never deal with it again. Q: Will this bolt fit my aftermarket billet filter head?A: If your aftermarket filter head uses the factory 1R-0750 mounting boss threads, yes. This bolt matches the OEM thread specifications exactly. For aftermarket heads with different thread specs, please verify before ordering. Q: Do I need to replace this bolt every time I change the filter?A: No. This stainless steel bolt is a one-time upgrade. Unlike the factory bolt that corrodes over time, this bolt will outlast your truck. Just apply fresh anti-seize during filter changes for extra insurance.Related Guides & Articles📖 Duramax Fuel Filter Change: LB7 through LML — Complete DIY Guide
