DESCRIPTION Product Overview The Trucktok 2019-2024 6.7L Cummins Chassis Fuel/Water Separator provides OEM-grade protection for later-generation Ram HD fuel systems, shielding sensitive high-pressure fuel pumps and precision fuel injectors. Its premium multi-layer media strips up to 99% of water and filters contaminants down to 5 microns before they reach your common-rail system. Engineered as a direct drop-in cartridge, this paper element fits perfectly inside the factory chassis housing. Each filter includes a heavy-duty nitrile O-ring to replace your old housing cap seal, guaranteeing a leak-free fit under high fuel pressures. This versatile element also fits 2020-2023 Ram 1500 3.0L EcoDiesel models. Key Features Multi-layer pleated cellulose captures microscopic rust, dirt, and abrasive contaminants, protecting high-pressure fuel pumps and sensitive common-rail injectors from premature wear. Strips up to 99% of emulsified water and moisture from diesel fuel, preventing fuel line freezing, injector corrosion, and power loss. Molded to exact OE physical dimensions for a perfect, hassle-free slip-in fit inside the factory chassis-mounted canister—no modifications or adapters required. Includes a replacement housing cap O-ring designed to withstand high under-chassis fuel pressures and exposure to ULSD/biodiesel without swelling or leaking. Replacement Interval Replace every 15,000 miles or 12 months (whichever comes first) under normal driving conditions. For severe-duty, commercial hauling, or frequent off-road use, shorten the interval to every 10,000 miles to safeguard your high-pressure fuel system. FAQ Q: Why is this chassis filter so critical for 2019+ Ram fuel systems? A: Later-generation 6.7L Cummins high-pressure common-rail (HPCR) systems have zero tolerance for water or debris. Moisture strips away the lubricating fuel film inside the high-pressure pump, leading to metal-on-metal wear and catastrophic failure. This filter is your primary line of defense. Q: What is the physical difference between 2013-2018 and 2019-2024 filters? A: The 2013-2018 trucks use a metal spin-on canister (68197867AA). The 2019-2024 trucks use a direct drop-in paper cartridge (68436631AA) that slips inside a reusable plastic housing. They are completely different designs and cannot be interchanged. Q: How often should I drain water from the separator housing? A: Drain it at every oil change (7,500–10,000 miles), or immediately if the "Water-in-Fuel" light illuminates on your dash. If you drive in cold winter climates or buy fuel from low-turnover stations, check it monthly. Q: Can I use this filter on a deleted or tuned truck? A: Yes. Tuned trucks run higher injection pressures and demands cleaner fuel to survive. This high-flow filter handles increased flow demands without restriction while maintaining its 99% water separation efficiency. Q: Should I replace this chassis separator and the engine-bay filter together? A: Yes. Both share the same 15,000-mile interval. Replacing only one shifts the restriction downstream. We highly recommend using a Dual Fuel Filter Kit to replace both simultaneously for complete protection.
