Key Features Complete All-in-One Kit: Filter head, spin-on element, water bowl, four fittings, and two plugs — no separate purchases needed. 10-Micron Filtration: High-efficiency cellulose media captures 99% of particles ≥10 microns, protecting injectors and fuel pumps from abrasive wear. Clear Visual Water Detection: Transparent nylon bowl with drain valve allows instant water level inspection and easy draining without disassembly. Racor S3240 / 120AT Compatible: Direct replacement for the most popular marine and industrial fuel water separator series on the market.

Apply 2-3 wraps of PTFE thread sealant tape on all NPT fittings — do not overtighten. Prime the filter element with clean diesel before first start to prevent air lock. Drain the water bowl monthly or whenever water is visible in the collection chamber. Replace the filter element every 100 engine hours or annually, whichever comes first. Frequently Asked Questions Q: Will this fit my Mercury outboard fuel system?A: Yes. The R12T uses standard NPT ZG1/4-19 ports compatible with Mercury, Yamaha, and Suzuki outboard fuel line fittings from 4 HP to 200 HP. The kit includes four brass adapters for flexible installation. Q: Is this a direct replacement for Racor S3240?A: Absolutely. The thread pattern and mounting dimensions are identical to the Racor S3240 / 120AT series. You can swap your existing element and bowl, or use the complete iFJF kit for a full refresh. Q: How do I know when to drain the water bowl?A: The clear nylon bowl allows visual water inspection. If you see a visible water layer or the red indicator ring floats up, open the bottom drain valve to purge. Check before every trip. Q: Can I use this for gasoline engines?A: Yes — compatible with both gasoline and diesel. For gasoline applications, drain the bowl more frequently as ethanol-blended fuels can attract moisture. Q: What replacement filter elements fit?A: Any 120AT-style spin-on filter element with the correct thread pattern. iFJF sells replacement R12T elements individually on our store. 📊 Independent Tear-Down: iFJF R12T vs Genuine Racor Third-party visual comparison — filter head, element, and canister cut open side by side Filter Head: Visually identical to genuine Racor — no notable differences found Filter Element: ~23 inches longer than OEM — more filtration media inside Canister Wall: Thicker than genuine Racor (20mm) Complete Kit: Includes 2 brass fittings, 2 port plugs, and PTFE tape — everything needed to install 📦 Related Products & Guides 🛒 Complete Your Fuel System: R12T Replacement Filter Element ($19.99) — Spare 10-micron spin-on cartridge R12T Filter Base / Head Only ($19.99) — Just need the aluminum head + fittings?

U58/9KIT Diesel Urea (DEF) Filter — SCR System Protection The iFJF U58/9KIT Urea Filter is a direct OEM-quality replacement for Mercedes-Benz and Detroit Diesel Selective Catalytic Reduction (SCR) systems. This critical filter prevents contaminants and crystallized DEF from clogging your SCR injector — a failure that can trigger limp mode and costly dealer repairs. Key Features Direct OEM Replacement: Engineered to match the exact filtration specifications of the factory filter — same micron rating, flow rate, and fitment High-Efficiency Media: Multi-layer synthetic filter media captures particles as small as 10 microns including crystallized urea deposits Prevents SCR Injector Failure: A clogged DEF injector is a $500+ repair. A clean filter is cheap insurance Chemical Resistant: Materials rated for continuous exposure to Diesel Exhaust Fluid (32.5% urea solution) Easy Access Installation: Typically located in the DEF tank or pump module — replaceable in 15-30 minutes Vehicle & Engine Compatibility Application Engine/Model Mercedes-Benz BlueTEC Diesel with OM642, OM651 engines (Sprinter, E-Class, GL-Class, ML-Class) Detroit Diesel DD13, DD15, DD16 engines with SCR (2010+) Freightliner Cascadia, M2 with Detroit DD13/DD15 Evobus / Setra OM 457 LA, OM 906 LA, OM 926 LA Cross-Reference Part Numbers Brand Part Number Mercedes-Benz OEM A0001421089, A 000 142 10 89 Detroit Diesel 2265672 Freightliner 2655824, 1421089 Aftermarket UF106, 4388378 Symptoms of a Clogged DEF Filter Check engine light with SCR-related fault codes (P20E8, P20E9, P204F) Reduced engine power / limp mode "DEF System Fault" or "Incorrect DEF Fluid" warning on dash Failed emissions test Poor DEF consumption (injector not spraying properly) Installation & Maintenance Replacement Interval: Every 100,000–150,000 miles or when SCR-related codes appear DEF Quality Matters: Always use ISO 22241 certified DEF fluid. Contaminated or expired DEF accelerates filter clogging Professional Tip: When replacing the filter, also inspect the DEF injector tip for crystallization — clean with warm water if needed FAQ Q: Will this fit a 2014 Mercedes Sprinter 2500 BlueTEC?A: Yes. The U58/9KIT is compatible with Sprinter vans equipped with the OM642 or OM651 BlueTEC diesel engine and SCR system. Q: How do I know if my DEF filter needs replacement?A: Common signs include SCR-related check engine codes (P20E8, P204F), reduced power mode, or DEF system warning messages. Many shops recommend replacement at 100,000–150,000 miles as preventive maintenance. Q: Can I clean the existing filter instead of replacing it?A: No. DEF filters are not serviceable — the media becomes saturated with crystallized urea and cannot be effectively cleaned. Replacement is required. Q: Is this compatible with Detroit DD15 engines?A: Yes. This filter fits Detroit DD13, DD15, and DD16 engines equipped with SCR aftertreatment systems (2010 and newer). Q: Will replacing this filter clear my check engine light?A: After replacement, you may need to clear the fault codes with an OBD-II scanner. The light should stay off if the filter was the root cause. If codes return, the DEF injector or pump may also need attention.Related Products Fuel Filter Housing for 2005-2013 Duramax 6.6L — 2500HD/3500HD 29531007 GMC, Ram 6.6L 2500HD, Duramax, Sierra, 2500, Silverado Tune Up Kit 140-3116 122-0836 149-2341-01 Filter 167-1638 Spark Plug for Onan RV 122-0833 Oil Filter for Cummins Onan RV Generator QD 3200 6000 8000 10000 12500 140-2897 Air Filter 3-Pack for Onan QD/HQD Generator Series

RV Air Conditioner Soft Start Kit — 364 Compatible Most RV air conditioners draw 50-70 amps on startup — enough to trip a 30A breaker or stall a portable generator. This soft start kit reduces inrush current by up to 70%, letting you run your A/C on a small 2000W generator, 30A shore power, or even a battery/inverter setup. Compatible with popular 364 soft start systems. Perfect for boondocking, campgrounds with limited power, or saving your generator from hard starts. Key Features 70% Startup Surge Reduction — Ramps the compressor gently instead of slamming it with full current. Your generator won't stall, your breaker won't trip. Runs on 2000W Generator — A standard 13,500 BTU RV A/C normally needs 3000W+ to start. With this kit, a 2000W generator is sufficient. 364 System Compatible — Plug-and-play replacement or upgrade for 364-type soft start systems. Same wiring, same footprint. Protects Your A/C Compressor — Soft starting reduces mechanical shock on the compressor, extending its service life. DIY Friendly — Includes wiring diagram and mounting hardware. Basic electrical knowledge required. 30-60 minute install. Universal Fit — Works with most rooftop RV air conditioners: Dometic, Coleman, Advent, Atwood, Furrion, and others. Compatibility Brand Models BTU Range Dometic Brisk Air II, Penguin II, Blizzard NXT 11,000 - 15,000 BTU Coleman Mach 1, Mach 3, Mach 8, Mach 10, Mach 15 9,200 - 15,000 BTU Advent AC135, AC150 13,500 - 15,000 BTU Atwood / Dometic Air Command, 15030 13,500 - 15,000 BTU Furrion Chill, FACR 13,500 - 15,500 BTU Technical Specifications Input Voltage: 110-120V AC, 60Hz Max Compressor: Up to 16,000 BTU Startup Current Reduction: 60-70% Package Includes: Soft start module, wiring harness, mounting bracket, hardware kit, installation guide Why Choose iFJF? Without a soft start, every A/C cycle puts enormous stress on your generator, breaker panel, and compressor. The result: tripped breakers on hot days, generator overloads, and premature compressor failure. Our soft start kit gives you freedom to camp anywhere — national park with 30A only, boondocking with a small generator, or driveway camping on a 15A household outlet. Frequently Asked Questions Q: Will this work with my RV's A/C unit?A: Compatible with most single-compressor rooftop RV A/C units up to 16,000 BTU. Check the compatibility table above. If your unit isn't listed, contact us with your make/model for confirmation. Q: Can I really run my A/C on a 2000W generator?A: Yes. A 13,500 BTU A/C normally needs 2800-3000W to start. The soft start drops startup surge by 60-70%, making a 2000W generator sufficient. Still need headroom for other loads like microwave. Q: Is this hard to install?A: Basic electrical skills required. Wiring into compressor circuit on the rooftop unit. Clear wiring diagram and hardware included. Typical install: 30-60 minutes. Professional install recommended if uncomfortable with 120V AC. Q: Will this damage my A/C compressor?A: No — it protects the compressor. Soft starting reduces mechanical shock and current inrush, actually extending compressor life. Same technology used in residential HVAC. Q: Does this work with inverter generators?A: Yes, inverter generators benefit the most. Their eco-mode can't handle hard-start surges. The soft start solves this perfectly. Q: Do I need one per A/C unit?A: Yes, each rooftop A/C needs its own soft start kit. Dual A/C setups require 2 kits.

385230325 RV Toilet Vacuum Breaker Kit — Hand Sprayer — Stop Leaks & Prevent Backflow A leaking vacuum breaker on your RV toilet doesn't just waste water — it can siphon contaminated water back into your fresh water system, cause odors, and damage your bathroom floor. The iFJF 385230325 Vacuum Breaker Kit is the correct dual-port replacement for Dometic/Sealand Traveler and VacuFlush toilets equipped with a hand sprayer. Unlike single-port alternatives, this kit includes the dedicated sprayer connection port — no adapters, no leaks, no compromises. Complete kit includes vacuum breaker body, integrated dual-seal check valve, all O-rings and gaskets, and stainless steel mounting hardware. Measures 3.25" L × 1.73" W × 3.65" H for exact drop-in fit. Key Features Hand Sprayer Compatible: Dual-port design with dedicated sprayer connection — no T-fittings or adapters that create leak points. Specifically for toilets WITH a hand sprayer. Complete Kit: Vacuum breaker body (3.25"L × 1.73"W × 3.65"H), dual-seal check valve, all O-rings, gaskets, and stainless steel hardware — everything needed. Backflow Prevention: Dual-seal check valve prevents contaminated water from siphoning back into your fresh water plumbing. Meets ABYC and RVIA code requirements. Durable Materials: High-impact ABS body withstands years of vibration from road travel. Nitrile seals resist holding tank chemicals and marine sanitation products. DIY-Friendly: 20-30 minute installation with basic hand tools. 1/2" NPT connections match factory plumbing. Compatibility Brand Series Models / Notes Dometic / Sealand Traveler 110, 111, 210, 211, 510, 511 (with hand sprayer) Dometic / Sealand VacuFlush All models with hand sprayer attachment ⚠️ Not Sure Which Kit? If there's a coiled hose behind your toilet connected to the breaker → this is your kit. No hose → order 385316906 (no sprayer). Specifications Specification Detail Part Number 385230325 Dimensions 3.25"L × 1.73"W × 3.65"H Material ABS Body / Nitrile Seals / Stainless Steel Hardware Connection 1/2" NPT — Dual Port (Water Inlet + Sprayer) Check Valve Dual-Seal, Integrated Symptoms of a Failed Vacuum Breaker Water leaking or spraying from behind the toilet pedestal — especially when the hand sprayer is used Continuous slow drip from the breaker housing Bowl fails to hold water after flushing Sewage odor near the toilet (backflow through failed check valve) Reduced sprayer pressure or water hammer when flushing Installation Steps Shut off water supply to the toilet. Flush to relieve system pressure. Disconnect the hand sprayer hose and water supply line from the old breaker. Remove the old vacuum breaker (typically 2 screws or threaded collar). Clean mounting surface and inspect for cracks or damage. Install new breaker with supplied gaskets — 2-3 wraps of Teflon tape on threaded connections. Reconnect sprayer hose and water line, turn on supply, test all connections for leaks. Why Choose iFJF? iFJF vacuum breaker kits are manufactured to OEM Dometic/Sealand specifications with upgraded nitrile seals for extended service life — especially important in hot climates where rubber seals degrade faster. US-based support and fast shipping from our American warehouse. Related Products 385316906 Vacuum Breaker Kit — No Hand Sprayer 4036ER2004A Washer Tub Bearing & Seal Kit Pressure Gauge for Sand Filter Pump Frequently Asked Questions Q: Does this fit toilets without a hand sprayer?A: No. If your Sealand/Dometic toilet does NOT have a hand sprayer, you need the 385316906 (single-port) vacuum breaker kit. This 385230325 has a dedicated sprayer port. Q: How long does installation take?A: 20-30 minutes. Accessing the back of the toilet in tight RV bathrooms is typically the most time-consuming part. A compact mirror and headlamp make it easier. Q: Do I need thread sealant or Teflon tape?A: Yes. Apply 2-3 wraps of Teflon tape to male threaded connections. Do not use pipe dope or liquid sealants — they can degrade the nitrile seals. Q: Why does my breaker leak only when I use the hand sprayer?A: This is a classic sign of a failed check valve inside the vacuum breaker. The sprayer back-pressures the system, and a worn seal can't hold. Replacement is the fix. Q: Will this stop sewage odors?A: If the odor is from backflow through a failed vacuum breaker — yes. If caused by a failed floor flange seal or holding tank vent, those may need separate repair. 📚 Related Guides & Articles Complete Onan Quiet Diesel RV Generator Tune-Up Why You Need a Bluetooth Kill Switch for Your RV or Truck

385311658 Flush Ball Ring Seal — Complete Dometic Bowl Seal Kit Slow bowl water loss or faint sewage odor in your RV bathroom almost always points to a worn flush ball seal ring. The iFJF 385311658 is an exact-replacement seal for the critical junction between the flush ball and toilet bowl in Dometic 300, 310, and 320 series gravity-flush toilets. Made from durable, chemical-resistant polymer, this seal restores the water-tight and odor-proof barrier in under 30 minutes — no tools required, installed entirely from above the bowl. Key Features Exact OEM Fit: Precision-molded to Dometic specifications for 300, 310, and 320 series toilets — drops into the seal groove without modification or trimming. Dual-Seal Function: Creates a positive water barrier to keep bowl water from draining into the holding tank AND an odor seal to prevent sewage gases from entering the bathroom. Chemical-Resistant Polymer: Engineered to withstand formaldehyde-based and enzyme-based holding tank treatments — won't swell, soften, or degrade. Tool-Free Installation: The only Dometic toilet repair that requires zero tools — accessed and replaced entirely from above the bowl in 20-30 minutes. Budget-Friendly Maintenance: The most affordable Dometic toilet seal on the market — replace prophylactically every 2 years for peace of mind. Compatibility Brand Series Toilet Type Dometic 300, 310, 320 Gravity-Flush (All Models) Specifications Spec Value Part Number 385311658 Material Chemical-Resistant Polymer Seal Type Flush Ball Ring / Bowl Seal Installation Tool-Free — Above Bowl Access Includes Seal Ring + Installation Grease Symptoms of a Failed Bowl Seal Bowl water drains completely within 1-2 hours of flushing Holding tank odor noticeable near toilet (especially on hot days) Mineral buildup or black residue visible around flush ball opening Toilet requires multiple flushes to clear waste (insufficient bowl water) Gurgling sounds from toilet when not in use Installation Guide (Tool-Free!) Turn off water supply to toilet. Flush and hold pedal to drain bowl completely. Step on flush pedal and hold open to expose the seal ring in the bowl opening. Use fingers or a plastic pry tool to lift the old seal ring out through the bowl — it sits in a groove around the opening. Clean the seal groove thoroughly with a rag — remove all mineral deposits and old grease. Apply a thin coat of included silicone grease to the new seal ring. Press the new seal firmly into the groove. Ensure it's fully seated all the way around. Release pedal, turn water on, fill bowl, and check for water retention. Frequently Asked Questions Q: My bowl is dry every morning — is this the fix?A: Yes, this is the classic symptom of a failed flush ball seal. The seal can no longer hold water in the bowl, so it slowly drains into the holding tank overnight. Replace the seal ring to restore water retention. Q: Do I need to remove the toilet from the floor?A: No. Unlike many RV toilet repairs, the flush ball seal is installed entirely from above the bowl. Simply hold the pedal open and access the seal groove through the bowl opening. No dismounting required. Q: How often should the flush ball seal be replaced?A: Replace every 2-3 years under normal use, or at the first sign of bowl water loss. If you full-time RV or use harsh holding tank chemicals, inspect annually. The seal is inexpensive — proactive replacement prevents odor problems. Q: Will this stop the holding tank odor in my bathroom?A: Yes, if the odor is coming through the toilet bowl. A worn seal allows tank gases to bypass the flush ball. Combined with good tank vent maintenance, a new seal eliminates bathroom odors. Q: Why does my seal keep failing quickly?A: Frequent seal failures usually indicate mineral buildup from hard water or abrasive chemical treatments. Use a water softener if you have hard water, and consider enzyme-based tank treatments instead of formaldehyde-based products. Q: Is this genuine Dometic or aftermarket?A: This is a high-quality aftermarket replacement manufactured to Dometic OEM specifications. It matches the exact dimensions and material properties of the factory seal at a significantly lower cost.

Cycle flush pedal several times to purge air. Inspect all connections for leaks. Adjust if needed. Frequently Asked Questions Q: My toilet keeps running — will this fix it?A: Yes, if water is continuously flowing into the bowl even when the pedal isn't pressed, the internal valve diaphragm has failed. Replacing the complete valve assembly is the proper repair. Q: Does this fit the Traveler 511 toilet?A: Yes. The 385314349 fits all Sealand Traveler series models (110, 111, 210, 211, 510, 511) with push-to-connect water fittings. Q: Do I need special tools?A: No. The quick-connect fittings are tool-free. You'll only need a screwdriver for the mounting screws. Complete installation typically takes 20-30 minutes. Q: Will this work with my well water / hard water system?A: Yes. The valve is designed to handle mineral-heavy water. The built-in inlet screen catches sediment and can be cleaned periodically to maintain flow rate. Q: Is this valve anti-siphon?A: Yes. The integrated check valve prevents backflow into your fresh water system, meeting RVIA plumbing standards for toilet water supply connections. Q: What causes water valve failure in RV toilets?A: The most common causes are mineral scale buildup jamming the diaphragm, chemical degradation of internal seals from holding tank treatments, freeze damage in un-winterized systems, and simple wear from years of use.

385310076 Duckbill Valve — Single Replacement for Sealand Vacuum Pumps When your Sealand VacuFlush toilet loses vacuum or cycles constantly, the culprit is almost always a worn duckbill valve. This iFJF 385310076 single replacement duckbill valve is manufactured from premium nitrile rubber and sized for all Sealand S-Series and T-Series vacuum generator pumps. Ideal for boat and RV owners who need to replace one failed valve or build a spare parts kit — without buying a full rebuild kit. Key Features Premium Nitrile Rubber: Withstands chemical exposure from holding tank treatments and mineral buildup — outlasts generic silicone valves. Single Valve Purchase: Buy exactly what you need. No waste, no unused parts. OEM-Spec Dimensions: Precise lip geometry ensures complete one-way seal. Drops into S12D, S24D, S32D, T12, T24, T32 without modification. Silicone Grease Included: Pre-lubricated for easy installation without tearing. Universal S-Series/T-Series Fit: Compatible with all Sealand vacuum generator pumps. Compatibility Series Models S-Series S12D, S24D, S32D, S115A, S12, 52A, S32 T-Series T12, T24, T32 VHT/VG VHT12, VHT24, VG4, VG5 Specifications Spec Value Part Number 385310076 Material Premium Nitrile Rubber Valve Type One-Way Duckbill Check Valve Quantity 1 (Single Pack) Includes Valve + Silicone Grease Packet When to Buy a Single Valve vs. 2-Pack Buy Single: Inlet valve failed but outlet still good. Building a spare parts kit for cruising or camping. Troubleshooting to isolate which valve is the problem. Buy 2-Pack: Both valves are original and over 2 years old. Complete pump rebuild recommended. Pump cycles every few minutes. Symptoms of Failed Duckbill Valves Pump runs continuously without building pressure Weak or incomplete flushes Pump cycles every few minutes without flushing Foul odor from vacuum tank area Hissing sound near pump during operation Installation Tips Turn off power at breaker. Open pump housing (4-6 screws). Note orientation: tapered beak must face toward holding tank. Remove old valve carefully. Clean mounting surfaces thoroughly. Apply included silicone grease to valve lip and press into place. Reassemble housing, restore power, test with 3-4 flushes. Check for vacuum hold — pump should not cycle within 2 minutes of idle. Frequently Asked Questions Q: How do I identify which valve is bad?A: Listen near each valve while pump runs. Hissing = leak at that valve. Vacuum bleeds immediately after pump stops = inlet valve failure. Pump slow to build vacuum but holds once achieved = outlet valve issue. Q: Should I buy one valve or the 2-pack?A: If both valves are original and over 2 years old, buy the 2-pack for a complete rebuild. If one failed prematurely (chemical damage, debris), a single replacement is sufficient. Q: How often should duckbill valves be replaced?A: Every 2-3 years under normal use. Liveaboards and full-time RVers should replace annually. Holding tank chemicals accelerate rubber degradation — inspect valves during annual maintenance. Q: Will non-OEM valves work as well as original?A: Our premium nitrile valves match OEM specifications and dimensions. Many marine mechanics report our nitrile compound outlasts OEM rubber in chemically-treated systems. Q: Can I install this myself?A: Absolutely. The job takes 15-20 minutes with basic hand tools (screwdriver). No specialized marine or RV knowledge required. Watch our installation video for step-by-step guidance. Q: What happens if I install it backward?A: The pump won't build vacuum because the valve will be forced open instead of sealed. The tapered beak MUST face toward the holding tank (away from the vacuum pump). If installed backward, simply flip it around.

Product Overview The 2-Pack FS1098 Fuel Water Separator for Cummins B6.7 / ISL8.9 delivers professional-grade fuel filtration for diesel engines. Manufactured with advanced synthetic media for superior contaminant capture and water separation, this filter protects your high-pressure common rail injection system from the microscopic particles and moisture that cause premature injector and pump failure. As diesel injection pressures climb past 30,000 PSI in modern engines, fuel cleanliness has never been more critical. A single tank of contaminated fuel can cause thousands in injector damage. This filter provides the first and most important line of defense for your fuel system. Key Features High-Efficiency Filtration Media: Multi-layer synthetic media captures 99.9% of particles at the rated micron level, exceeding standard cellulose elements in both efficiency and dirt-holding capacity. Advanced Water Separation: Coalescing technology removes emulsified and free water from diesel fuel, preventing injector tip erosion and microbial growth. OEM-Spec Construction: Manufactured to ISO 9001 quality standards with precision-threaded base plate, anti-drain back valve, and high-burst-strength canister. Direct Fit Replacement: Engineered as a drop-in replacement — no modifications, adapters, or special tools required. Extended Service Life: Higher dirt-holding capacity means longer intervals between changes, reducing downtime and per-mile filtration costs. Compatibility Specification Detail Engine Cummins B6.7, ISL8.9, L9 Diesel Application Commercial Trucks, RVs, Buses Replaces Part # FS1098, 5319680, 5308722 Micron Rating 2-10 Micron Absolute Filter Type Spin-On with Water Separation Why Upgrade Your Fuel Filtration? Extended Injector Life: Injectors operating at 30,000+ PSI have micron-level clearances. Better filtration means injectors lasting 200K+ miles instead of failing at 100K. Improved Cold-Weather Reliability: Superior water separation prevents ice crystal formation in fuel lines during winter. Reduced Maintenance Costs: Preventing one HPFP failure saves $5,000-$10,000 — the cost of a lifetime of premium filters. Better Fuel Economy: Clean injectors atomize fuel more efficiently, maintaining optimal combustion over the vehicle lifetime. Installation Guide Safety First: Park on level ground, engage parking brake, allow engine to cool. Have a drain pan ready. Relieve Fuel Pressure: Remove fuel cap. On some models, pull fuel pump fuse and crank briefly. Remove Old Filter: Use oil filter wrench to loosen. Unscrew by hand and lower into drain pan. Prep New Filter: Apply thin film of clean diesel to gasket. Pre-fill if housing design allows. Install: Spin on by hand until gasket contacts. Tighten 3/4 to 1 full turn. DO NOT over-tighten with wrench. Prime System: Cycle key ON (not START) 5-6 times for 30 seconds each to purge air. Check for leaks. Start & Verify: Start engine, check for leaks at idle, let run 2 minutes, recheck. Dispose of old filter properly. Frequently Asked Questions Q: What engines does this fit?A: Fits Cummins B6.7, ISL8.9, and L9 diesel engines in Freightliner M2, International MV, Blue Bird Vision buses, motorhomes, and commercial vehicles from 2010-present. Replaces OEM part numbers 5319680 and 5308722. Q: How is this different from the fuel filter?A: FS1098 is a fuel water separator — it removes water, sediment, and larger particles BEFORE fuel enters the main filter. This 2-stage filtration protects the high-pressure common rail system. Replace both filters together. Q: What micron rating?A: 10-micron nominal filtration with 98% water separation efficiency. Integrated PCV (pressure control valve) maintains consistent fuel pressure. Exceeds OEM water removal performance. Q: How often should I drain the water separator?A: Drain the water bowl weekly during regular operation or when the WIF (Water-In-Fuel) warning light illuminates. For sitting vehicles, drain monthly. Water accumulation is higher in humid climates and with biodiesel blends above B5. Q: Can I use this on my RV Cummins generator?A: Yes. If your RV has a Cummins Onan generator with B6.7 or ISL engine platform, this is a direct fit. Verify generator model number — common on class A diesel pushers with Onan QD series.
