Save money and protect your engine! In this step-by-step DIY tutorial, learn how to change both fuel filters on a RAM 2500 Cummins 6.7L Turbo Diesel. Replacing your front engine-mounted fuel filter and rear frame-rail water separator is one of the most critical maintenance tasks to prevent costly fuel injector failures and fuel pump damage.
Whether you drive a Ram 2500 or Ram 3500, this complete maintenance guide covers everything you need to know—from tools required to properly priming the fuel system so your truck starts right up without air locks.

4:40 - Removing Rear Fuel Filter Water Sensor
10:30 - Removing & Replacing the Under-Hood Fuel Filter
9:20 - Priming the Fuel System (Crucial Step!)
20:50 - Starting the Truck & Checking for Leaks
23:45 - Resetting the Fuel Filter Life on the Dash
🛠️ Parts & Tools Used in This Video:
Check your parts and I recommend using Geno's Garage to ensure you get quality filters and service.
Mopar Engine Fuel Filter: (Part # 68157291AA)
Mopar Rear Fuel/Water Separator: (Part # 68197867AA)
Tools Needed: 28mm or 1-1/8" socket, socket extension, drain pan, clean rags, and diesel fuel additive/clean lube.
💡 Pro Tips:
Always pre-fill or prime the fuel system properly by cycling the ignition key (run position) before cranking the engine to avoid starving the High-Pressure Fuel Pump (CP3/CP4).
Lube the new O-rings with clean diesel or fuel additive before installation to prevent tearing.
