Overview The iFJF 68268285AC Fuel Water Separator Assembly is a direct OEM-grade replacement for the chassis-mounted fuel filter housing on 2013-2018 Ram 2500, 3500, 4500, and 5500 trucks equipped with the 6.7L Cummins Turbo Diesel engine. This complete assembly includes the integrated primer pump, water-in-fuel (WIF) sensor connector, drain valve, and mounting bracket — everything you need for a drop-in replacement. Water contamination is the #1 cause of premature injector failure in modern diesel engines. The high-pressure CP4.2 injection pump and piezo injectors in the 6.7L Cummins have extremely tight clearances — even a few drops of water passing through can cause catastrophic damage ($4,000-$8,000 repair cost). This separator assembly ensures reliable water separation and fuel filtration at every fill-up. Key Features Complete Assembly — Includes filter housing, primer pump, WIF sensor port, drain valve, and mounting bracket — pre-assembled OEM-Grade Construction — Manufactured to OE specifications with high-grade composite materials resistant to diesel fuel and biodiesel blends Integrated Primer Pump — Makes fuel system priming after filter changes fast and tool-free — no more cranking the starter WIF Sensor Port — Direct plug-and-play with factory water-in-fuel sensor for dashboard water detection warning Easy Drain Valve — Accessible drain port allows quick water purging during routine maintenance without removing the filter Protects $4,000+ Fuel System — Effective water separation prevents catastrophic CP4.2 pump and injector failure Direct Cross-Reference — Replaces Mopar 68268285AC, 68197866AA, 68197866AB, 68197866AC, 68268285AB Chassis-Mounted Design — Factory-correct location under driver-side frame rail for easy access during oil changes Technical Specifications Specification Details Part Number 68268285AC (Replaces 68197866AA/AB/AC, 68268285AB) Vehicle Fitment 2013-2018 Ram 2500/3500/4500/5500 6.7L Cummins Filter Type Fuel Water Separator Assembly (Chassis-Mounted) Includes Filter Housing, Primer Pump, WIF Sensor Port, Drain Valve, Bracket Material High-Grade Composite / Aluminum Bracket Compatibility Year Make Model Engine 2013-2018 Ram 2500 / 3500 6.7L Cummins I6 Turbo Diesel 2013-2018 Ram 4500 / 5500 (Chassis Cab) 6.7L Cummins I6 Turbo Diesel Installation Guide Relieve Fuel Pressure — Open the fuel filler cap to release tank pressure Locate Assembly — Chassis-mounted housing on the driver-side frame rail, near the fuel tank Disconnect Quick-Connect Lines — Use fuel line disconnect tool; have rags ready for fuel spillage Unplug WIF Sensor — Disconnect the electrical connector from the water-in-fuel sensor Remove Mounting Bolts — Typically 2-3 bolts securing the housing bracket to the frame Install New Assembly — Bolt in the iFJF replacement, reconnect lines and WIF sensor Prime System — Pump the integrated primer until firm resistance is felt Cycle Key & Start — Cycle key to "Run" (not start) 3 times to prime, then start and inspect for leaks Why Replace Your Water Separator? Prevent $4,000-$8,000 Injector Failure: The CP4.2 high-pressure pump and Bosch piezo injectors are extremely sensitive to water. A cracked housing or leaking primer pump compromises water separation — allowing water to reach the injection system. Replacement is far cheaper than injector/pump repair. Stop Diesel Leaks: Cracked filter housings and degraded seals create a fire hazard and fail DOT inspections. A complete assembly replaces all wear-prone components in one service. Restore Reliable Priming: A worn primer pump that won't build pressure makes every filter change a frustrating battle with air-locked fuel lines. FAQ Q: How often should the water separator assembly be replaced?A: The filter element inside the housing should be replaced every 15,000-30,000 miles. The complete housing assembly typically lasts the life of the vehicle unless damaged. Replace the housing if you notice fuel leaks, primer pump failure, or a cracked housing body. Q: Does this include the actual fuel filter element?A: No. This is the housing assembly. You will need to transfer your existing filter element or install a new one. Compatible filter elements include Mopar 68157291AA and aftermarket equivalents. Q: Will this fit my 2019+ Ram with the 6.7L Cummins?A: No. 2019+ Ram HD trucks (5th Gen) use a different fuel filter housing design. This assembly is specifically for 2013-2018 model years. Verify your OEM part number before ordering. Q: Why does my Ram have TWO fuel filters?A: The 6.7L Cummins uses a two-stage filtration system: (1) this chassis-mounted water separator removes water and large particles, then (2) the engine-mounted fuel filter provides final fine filtration before the high-pressure CP4.2 pump. Q: How do I know if my housing is cracked?A: Look for diesel fuel drips or wetness on the housing body, a strong diesel smell near the driver-side frame rail, or difficult priming after filter changes. Cracked housings are common in cold climates where trapped water freezes and expands. Q: Can I drain water without removing the filter?A: Yes! The integrated drain valve on the bottom allows quick water purging. Place a catch container underneath, open the valve, and drain until clean fuel appears. Do this every oil change or whenever the WIF dashboard light illuminates. Q: Is this compatible with B20 biodiesel?A: This housing is manufactured from biodiesel-resistant composite materials rated for B5-B20 blends. Follow your engine manufacturer's biodiesel usage guidelines and reduced filter change intervals when running biodiesel. Q: How does this compare to the OEM Mopar assembly?A: Manufactured to OE specifications using equivalent materials and processes. Same fit, function, and durability at a significantly lower price point. All mounting points, line connections, and sensor ports match factory dimensions exactly. 📚 Related Guides & Articles iFJF Guides & Resources — Expert Tips, Installation Tutorials & Buying Guides 📖 Related Guide: FS1098 Fuel Water Separator Install Guide for Cummins B6.7 & ISL8.9 — Torque Specs, Cross-Reference & DIY Steps

Product Overview The AF55015 is a heavy-duty cylindrical air filter element designed for Cummins QSB6.7, QSC, QSC9, and QSL9 industrial and marine diesel engines. Commonly found in construction equipment, marine vessels, generators, compressors, and agricultural machinery, these engines operate in some of the harshest environments on earth — from dusty construction sites to salt-spray marine applications. This filter provides the robust filtration and high airflow capacity these engines demand. Key Features Industrial-Grade Filtration: Engineered for continuous-duty applications — construction equipment, marine propulsion, generator sets, and compressor drives Wide Cummins Compatibility: Fits QSB6.7 (6-cylinder), QSC (8.3L), QSC9, and QSL9 (8.9L) engine platforms across multiple equipment brands Full Cross-Reference: Replaces AF55015, PA31000, 5261250, WA10715, AF2501, and 500715 Direct Flow 1200 Series: Part of the high-capacity Direct Flow filtration family with superior dust-holding capacity Cylindrical Design: Radial seal configuration ensures positive sealing even under vibration and thermal cycling Moisture-Resistant Media: Treated to resist moisture absorption in marine and high-humidity environments Engine & Equipment Compatibility Engine Platform Displacement Common Applications Cummins QSB6.7 6.7L I6 Excavators, wheel loaders, forklifts, generators, marine Cummins QSC / QSC9 8.3L I6 Bulldozers, graders, marine propulsion, industrial pumps Cummins QSL9 8.9L I6 Cranes, drill rigs, agricultural tractors, generator sets Specifications Specification Value Part Number AF55015 Cross References PA31000, 5261250, WA10715, AF2501, 500715 Filter Type Cylindrical / Radial Seal Air Filter Series Direct Flow 1200 Media Type High-Capacity Cellulose with Moisture-Resistant Treatment Seal Type Radial Lip Seal (integrated) Service Interval 500 hours (standard), 250 hours (severe dust) Outer Diameter Approx. 9 inches Length Approx. 14 inches Why Proper Air Filtration Matters for Industrial Diesels Industrial diesel engines ingest massive volumes of air — the QSB6.7 at full load consumes over 400 cubic feet of air per minute. Any dust or debris that bypasses the air filter becomes an abrasive inside the cylinders, accelerating piston ring, cylinder wall, and valve seat wear. In dusty environments common to construction and agriculture, a single hour of operation with a compromised filter can cause more engine wear than 100 hours with a clean filter. For marine applications, salt-laden air adds corrosion risk to the equation — making proper filtration doubly critical. Installation Tips Locate the air filter housing — typically a cylindrical metal or plastic canister near the engine intake Release the housing cover latches or band clamp Remove the cover and slide out the old filter element Inspect the housing interior and clean any accumulated dust or debris Check the safety element (inner filter) if equipped — replace if visibly dirty (sold separately) Install the new AF55015 filter — ensure the radial seal seats evenly against the housing flange Replace the cover and secure all latches/clamps — the filter must be held firmly in place Reset the air filter restriction indicator if equipped (press the reset button on the indicator) Frequently Asked Questions Q: Does this fit my Bobcat with a Cummins QSB6.7?A: Many Bobcat models with the QSB6.7 use this filter, but always verify your specific machine's filter part number. Check your operator's manual or the part number on your existing filter before ordering. Q: How often should I change this filter in marine use?A: For marine engines in saltwater environments, inspect every 250 hours and replace annually regardless of hours. Salt-laden air is more corrosive and can degrade filter media faster than inland air. Always check for signs of salt crystal formation on the filter element. Q: What's the difference between the AF55015 and AF55020?A: The AF55015 is designed for the larger QSB6.7/QSC/QSL9 engine family, while the AF55020 fits the smaller QSF2.8/QSF3.8/QSB4.5 platforms. They are not interchangeable — the dimensions and airflow ratings differ significantly. Q: Can I clean this filter with compressed air?A: Not recommended. Using compressed air can damage the filter media and create invisible tears that allow dust to pass through. This is a disposable filter — replace it when service is due. The cost of a new filter is negligible compared to the cost of premature engine wear. Q: What happens if the air filter restriction indicator shows red?A: A red restriction indicator means the filter is clogged past the safe operating limit. Continued operation with a restricted filter causes excessive fuel consumption, power loss, increased exhaust smoke, and potential turbocharger damage. Replace the filter immediately and reset the indicator.

Key Features Direct OEM Fit: Drop-in replacement for Cummins part number 904-7904, also replaces 3685528, CV50617, CV50634 High Filtration Efficiency: Captures oil mist and particulates from crankcase gases, keeping your intake and turbocharger clean Heavy-Duty Construction: Built for the extreme operating conditions of Class 8 trucks — high mileage, high heat, and continuous duty cycles Emission System Protection: Clean crankcase ventilation reduces carbon buildup on EGR valves, DPF filters, and turbocharger components Easy Installation: Bolt-on replacement — typically 15-20 minutes with basic hand tools Compatibility Engine Make/Model Years Cummins ISX 11.9L Kenworth T680 2010–2024 Cummins ISX 11.9L Kenworth T800 2010–2024 Cummins ISX 11.9L Kenworth T880 2013–2024 Cummins ISX 11.9L Kenworth W900 2010–2024 Cummins ISX 11.9L Peterbilt 365 2010–2024 Cummins ISX 11.9L Peterbilt 567 2013–2024 Specifications Specification Value Part Number 904-7904 Cross References 3685528, CV50617, CV50634 Filter Type Crankcase Ventilation / Breather Engine Application Cummins ISX 11.9L Diesel Material Synthetic Media with Metal Housing Replacement Interval Every 100,000 miles or annually Why Replace Your Crankcase Breather? A clogged or failed crankcase breather filter leads to excessive crankcase pressure, oil leaks from seals and gaskets, turbocharger oil contamination, and increased oil consumption. On ISX engines, a failed breather is one of the most common causes of rear main seal failure — a repair that costs $2,000+. Replacing this $30 filter on schedule is the cheapest engine insurance you can buy. Installation Tips Locate the breather housing on the passenger side of the engine block (mid-engine, near the air compressor) Remove the breather housing cover bolts (typically 4 bolts, 10mm) Remove old filter element — note orientation for new filter installation Clean housing interior with shop rag to remove accumulated oil residue Install new 904-7904 filter element in correct orientation Replace cover gasket if worn or damaged (sold separately) Torque housing bolts to OEM specification (typically 18 ft-lbs) Frequently Asked Questions Q: How often should I replace the 904-7904 crankcase breather?A: Cummins recommends replacement every 100,000 miles or 12 months, whichever comes first. For trucks operating in severe dust, high idle time, or extreme temperature conditions, consider replacing every 75,000 miles. Q: What are the symptoms of a clogged crankcase breather?A: Common symptoms include: oil leaks from front/rear main seals, excessive blow-by from the oil fill cap, increased oil consumption, oil in the turbocharger inlet, and in severe cases — the dipstick popping out under crankcase pressure. Q: Does this fit my Peterbilt 389 with ISX?A: Yes, if your Peterbilt 389 has the Cummins ISX 11.9L (not the ISX 15L or X15), this filter will fit. The ISX 11.9L was used in many vocational and regional haul configurations from 2010 onward. Q: Is this the same as the Cummins OEM part?A: This is an aftermarket replacement manufactured to meet or exceed OEM specifications. It provides the same filtration efficiency and durability as the Cummins-branded part at a fraction of the cost. Q: Can a bad breather filter cause DPF issues?A: Yes. Excessive oil mist from a failed breather enters the intake tract, contributing to carbon buildup in the EGR cooler, DPF, and turbocharger. This increases regeneration frequency and can lead to premature DPF failure.

Product Overview The B085011 is a primary round air filter element designed for diesel engine compartments in heavy equipment, commercial trucks, and industrial applications. This cylindrical filter serves as the first stage of engine air filtration, capturing coarse to medium particulates before air reaches the secondary/safety filter. Built for high-dust environments, it provides the dirt-holding capacity and airflow volume that medium to large diesel engines demand. Key Features Wide Cross-Reference Compatibility: Replaces B085011, CA6818, 46637, AH1141, and PA2818 — covering multiple OEM and aftermarket part number systems Primary Stage Filtration: Designed as the outer/primary element in two-stage air filtration systems — pair with the appropriate safety/inner filter for complete protection High Dirt-Holding Capacity: Pleated cellulose media with deep dirt-loading channels extends service intervals in dusty operating conditions Universal Round Design: Fits numerous engine compartment air cleaner housings — verify dimensions before ordering to confirm fitment Heavy-Duty Construction: Reinforced metal end caps and center tube prevent collapse under high vacuum conditions Moisture Resistant: Treated media resists water absorption from rain, humidity, and engine compartment condensation Specifications Specification Value Part Number B085011 Cross References CA6818, 46637, AH1141, PA2818 Filter Type Primary Round Air Filter (Cylindrical) Media Type Heavy-Duty Pleated Cellulose End Cap Material Galvanized Steel Center Tube Perforated Steel Seal Type Radial Lip Seal (Integrated Gasket) Service Interval 500 hours or when restriction indicator shows red Application Diesel Engine Compartment Air Cleaner Housings Installation Guide Locate the cylindrical air cleaner housing in the engine compartment Release the housing cover — typically a wing nut, band clamp, or spring latches Remove the cover and slide out the old primary filter Inspect the safety/inner filter (if equipped) — do not remove unless replacing; the safety filter should only be replaced, never cleaned Wipe the housing interior clean with a damp cloth — avoid introducing dust into the clean-air side Check the housing seal and cover gasket for cracks or damage Install the new B085011 filter — ensure the radial seal seats evenly and the filter centers properly Replace the cover and secure all fasteners Reset the air filter restriction indicator (press the reset button) Start the engine and check for unusual intake noise or warning indicators Frequently Asked Questions Q: What equipment uses the B085011 filter?A: This filter is used across multiple diesel engine applications where a round primary filter of this specific size is spec'd. Applications include heavy trucks, construction equipment, agricultural machinery, generator sets, and industrial engine packages. Always cross-reference your existing filter number or measure your housing to confirm fitment. Q: Is this a primary or secondary filter?A: This is a PRIMARY (outer) filter. In two-stage air cleaner systems, the primary filter captures the majority of contaminants, while the safety/inner filter provides backup protection during primary filter service. This B085011 is the primary element. Q: Can I clean and reuse this filter?A: Not recommended. While some operators attempt to blow out round filters with compressed air, this practice often damages the media, creates invisible tears, and forces dirt deeper into the filter. For the cost of a replacement compared to the cost of engine damage, replacement is always the safer option. Q: How do I know what size filter I need?A: Measure your existing filter: outer diameter, inner diameter (the open center hole), and overall length/height. Compare these measurements against known filter specifications. Alternatively, cross-reference the part number on your existing filter. Q: What happens if the air filter gets wet?A: A wet air filter restricts airflow dramatically and can cause the engine to run rich, smoke, and lose power. In severe cases, water-saturated media can collapse, allowing unfiltered air into the engine. If your filter gets wet (e.g., from pressure washing the engine bay), replace it immediately.

Both filters fit the Duramax van platform, but for different engine generations: A2959C: 2006–2016 LLY/LBZ/LMM engine family (earlier Duramax van engines) A3140C: 2010–2016 LGH/LML engine family (later Duramax van engines with DPF/DEF emissions) If your van is a 2010–2016 model with the LGH or LML engine, the A3140C is the correct filter. Check your build sheet or VIN to confirm your engine code. Installation Guide Park on level ground, set parking brake, open hood Locate air filter housing — passenger side of engine bay, rectangular black plastic box Release the housing clips (4–6 clips around perimeter) or remove screws if equipped Lift the top cover — careful not to dislodge the MAF sensor wiring harness Remove old filter — note the direction of the airflow arrow printed on the filter frame Clean housing interior: vacuum out leaves, dust, or debris accumulated at the bottom Install new A3140C filter — airflow arrow should point toward the engine (intake tube side) Replace cover and secure all clips — press firmly on each clip until you hear it click Start engine, check for any unusual intake noise or warning lights Frequently Asked Questions Q: Will this fit my 2014 Chevy Express 3500 diesel cargo van?A: Yes. The A3140C is the correct filter for any 2010–2016 Express or Savana 2500/3500/4500 with the 6.6L Duramax diesel. Verify your engine code is LGH or LML for 100% confirmation. Q: Can I use the A2959C instead?A: While both filters share similar dimensions, the A2959C is designed for earlier LLY/LBZ/LMM engines (2006–2010). The A3140C is specifically engineered for the LGH/LML engine's airflow and filtration requirements. Using the correct part number ensures optimal performance. Q: What happens if I don't change my air filter on schedule?A: A restricted air filter reduces fuel economy by 3-10%, increases turbo lag, elevates EGTs, can trigger DPF regeneration issues, and in severe cases, may cause turbocharger damage from overspeed conditions. On a fleet vehicle, the fuel cost alone from a dirty filter can exceed $200/month with heavy use. Q: Is this filter pre-oiled like a K&N?A: No. This is a dry media filter — it requires no oiling. Dry filters are preferred for diesel applications with MAF sensors, as oil from reusable filters can contaminate the MAF sensor element and cause inaccurate readings. Q: How do I know when to replace vs just clean?A: This is a disposable filter — it should be replaced, not cleaned. Hold the filter up to a light source; if you cannot see light through the media, it's past due for replacement. If tapping the filter releases a cloud of dust, it's been overdue for a while.

Used in compact to mid-size equipment. AF55015: Larger form factor for QSB6.7, QSC, and QSL9 (6.7L–8.9L engines). Used in full-size construction and marine equipment. Always verify your engine model and existing filter part number — these filters are not interchangeable due to different housing sizes and airflow requirements. Installation Instructions Locate the cylindrical air filter housing — usually mounted near the engine with a band clamp or latches securing the cover Release the cover fasteners and remove the cover Slide out the old filter element — note orientation if marked Inspect the housing interior — wipe clean with a dry cloth, check for any damage or corrosion Check the safety element (inner filter) if your housing is a two-stage design — replace if dirty (sold separately) Slide the new AF55020 filter into the housing — the radial seal should seat flush against the housing flange Replace the cover — ensure the filter is centered and the cover seats evenly Secure all fasteners — do not overtighten band clamps as this can distort the housing Reset the air filter restriction indicator if equipped Frequently Asked Questions Q: Will this fit my Bobcat T770 compact track loader?A: The Bobcat T770 typically uses a Kubota engine, not a Cummins. However, many Bobcat E-series and newer compact equipment models use Cummins QSF3.8 engines. Always verify your specific machine's engine make and model before ordering. Q: How often should I change the air filter on a skid-steer?A: Skid-steers operating in demolition, grading, or agricultural applications should have air filters inspected every 250 hours and replaced at 500 hours or when the restriction indicator shows red — whichever comes first. Dusty conditions can cut service life in half. Q: Does this include the safety/inner filter?A: No. This listing is for the primary (outer) AF55020 filter only. The safety/inner filter is sold separately. The safety element should be replaced every third primary filter change or whenever it appears dirty — never clean and reuse a safety filter. Q: Can a dirty air filter cause black smoke from the exhaust?A: Yes. A restricted air filter creates a rich fuel condition (too much fuel, not enough air), which produces black smoke. On modern electronically-controlled Cummins engines, the ECM will typically derate the engine to prevent damage, but black smoke and power loss are classic signs of a clogged air filter. Q: Is this filter suitable for marine use?A: The AF55020 is designed primarily for land-based industrial applications. While the QSB4.5 is sometimes used in smaller marine vessels, confirm your specific marine engine's air filtration requirements. Marine applications often require additional moisture and salt-spray resistance.

Premium Oil Filtration for Cummins Compact Diesels The LF16352 spin-on oil filter is the standard lube filter for Cummins ISF 3.8L and QSF 2.8L diesel engines — the compact powerplants found in delivery trucks, marine auxiliaries, construction equipment, and agricultural machinery. Our replacement filter meets or exceeds OEM filtration specifications to protect your engine's bearings, turbocharger, and hydraulic systems from oil-borne contaminants. Why Oil Filtration Matters for Small Diesels Compact diesel engines like the ISF3.8 and QSF2.8 run at higher RPM than their big-bore counterparts, generating more oil shear and contaminants per displacement. A high-quality oil filter with consistent micron rating is essential for maintaining oil pressure, preventing turbo bearing wear, and extending oil change intervals. Compatibility Engine Displacement Application Cummins ISF 3.8 3.8L I4 Delivery trucks, buses, construction equipment Cummins QSF 2.8 2.8L I4 Marine auxiliary, compact construction, ag equipment Cross-Reference Part Numbers: Fleetguard LF16352, Donaldson P556352, Baldwin B40050, Sakura SO10116, Mann SP96023 Specifications Specification Detail Type Spin-on full-flow lube oil filter Micron Rating 15 micron nominal — ≥95% efficiency Thread Size Standard metric — direct spin-on replacement Anti-Drain Back Valve Yes — silicone valve prevents dry starts Bypass Valve Yes — integrated pressure relief for cold starts Gasket Pre-lubricated nitrile rubber — no leaks, easy removal Why Choose iFJF? OEM-equivalent filtration — 15-micron efficiency matches Fleetguard LF16352 specs Silicone anti-drain valve — Superior to rubber — stays flexible in cold weather Heavy-duty canister — Burst-tested to 5x rated operating pressure Pre-lubed gasket — Easy spin-on, easy spin-off at next oil change Universal fit — Cross-references to 6+ major filter brands Frequently Asked Questions Q: What's the oil change interval with this filter?A: Cummins recommends oil changes every 500 hours or 6 months for ISF3.8/QSF2.8 engines under normal operating conditions. Severe duty (high dust, high idle time) requires more frequent changes — consult your equipment manual. Q: Does this filter have a bypass valve?A: Yes. An internal bypass valve opens at approximately 12-15 PSI differential pressure to ensure oil flow during cold starts or if the filter becomes clogged. The anti-drain back valve keeps oil in the filter when the engine is off for instant pressure on startup. Q: Is this filter suitable for marine use?A: Yes. The filter is compatible with QSF2.8 marine auxiliary engines. Always follow your marine engine manufacturer's oil specification and change interval recommendations. Q: How does this compare to the Fleetguard LF16352?A: This filter is manufactured to the same 15-micron filtration standard as the Fleetguard OEM filter. It features equivalent media area, bypass valve calibration, and anti-drain valve performance. Q: Can I use this on a Cummins ISB or ISC engine?A: No. The LF16352 is designed specifically for ISF3.8 and QSF2.8 engines. Larger engines (ISB, ISC, ISL, ISX) require different filter models. Always verify the part number against your engine's manual.
