❓ FAQ
Q: Where is this fuel/water separator filter located on my Ram truck?
A: The Mopar 68197867AB is the rear, frame-mounted primary fuel filter. On 2013–2018 Ram 2500 through 5500 trucks, it is located underneath the truck bed, mounted to the frame rail right next to the fuel tank. This is separate from the secondary fuel filter, which is located under the hood in the engine bay.
Q: Does this filter include the built-in sensor, or do I reuse the old one?
A: This filter has a threaded port at the bottom designed to accept the factory Water-In-Fuel (WIF) sensor. The replacement filter does not come with a new sensor; you will unscrew your existing WIF sensor from the old filter, swap the rubber O-ring seal, and thread it into the bottom of the new Mopar filter before installation.
Q: What is the correct replacement procedure after spinning the new filter on?
A: Because this filter is installed empty, you must prime the fuel system before starting the truck to prevent running the fuel pump dry. Do not attempt to crank the engine immediately. Instead, turn the ignition key to the "RUN" position (without starting the engine) for about 10–15 seconds to let the electric lift pump push fuel back into the filter. Repeat this key cycle 3 to 5 times before starting the engine, then check the frame rail for any signs of leaks.
