❓ FAQ
Q: Where is this fuel filter located, and does my truck have more than one?
A: The Mopar 68235275AA is a rear, frame-mounted fuel filter cartridge. It drops into the water separator filter housing located underneath the truck bed on the frame rail, right next to the fuel tank. If your Ram truck is a 2013 or newer model, it uses a dual-filter system. This frame-mounted filter acts as your primary water separator, while a second, distinct cartridge-style filter (Mopar 68157291AA) is located under the hood in the engine bay. For complete fuel system protection, both filters should be changed at the same interval.
Q: What specific engine and model year range does this filter fit?
A: This filter is specifically engineered for heavy-duty Ram 2500, 3500, 4500, and 5500 trucks built between 2013 and 2020 equipped with the 6.7L Cummins inline-six turbo diesel engine. It is tailored to handle the high flow rates and strict water separation requirements of the high-pressure common rail fuel system used during these production years.
Q: What are the exact step-by-step instructions for changing this filter and priming the fuel system?
A: Because this filter is positioned on the frame rail below the fuel tank level, a precise replacement routine is necessary to prevent a continuous fuel spill and to correctly purge air out of the system before restarting your truck:
Locate the frame-mounted filter canister underneath the truck bed near the fuel tank. Turn the twist-valve drain knob at the bottom of the housing counterclockwise to allow the water and trapped diesel fuel to drain out completely into your catch pan. Close the valve tightly when it stops draining.
Use a 1-1/8 inch (28mm) socket or an appropriate filter cap wrench to unscrew the bottom housing cap counterclockwise. Carefully lower the cap straight down, as it will still contain some residual fuel.
Pull the old, dirty filter cartridge straight out of the housing cap and discard it. Remove the old rubber O-ring seal from the threads of the cap. Clean the cap thoroughly, snap the new 68235275AA filter element into the cap, install the new lubricated O-ring from the kit, and wipe a light film of clean diesel fuel onto the seal.
Guide the cap and new filter assembly back up into the frame housing. Thread it clockwise by hand first to guarantee it isn't cross-threaded, then use your socket to torque it down snug until it bottoms out completely. Ensure the bottom drain valve remains fully shut.
Do not crank the engine immediately. Turn the ignition key to the "RUN" position (or press the Start button without holding the brake pedal) and leave it there for 10–15 seconds. You will hear the electric lift pump hum as it fills the dry frame housing. Cycle the ignition off and repeat this priming process 3 to 5 times to safely bleed all remaining air out of the lines before starting the truck. Check the frame rail for any leaks.
