Protect Your 6.7L Cummins From a $10,000 Fuel System Failure
The Ram 6.7L Cummins is a million-mile engine — but only if you protect the fuel system. The CP4.2 high-pressure fuel pump used in 2013–2018 Ram HD trucks is notoriously vulnerable to contamination. Water or debris in your diesel will destroy this pump in seconds, sending metal shrapnel through your entire fuel system. The repair bill? $8,000–$12,000 at the dealership.
Your first and most critical line of defense is a high-quality fuel filter water separator. This iFJF kit gives you exactly that — at a fraction of what the dealership charges.

When to Replace Your Fuel Filter
Ram recommends replacing the fuel filter every 15,000 miles or 12 months under normal conditions. If you tow heavy, idle frequently, or fuel up at job-site tanks, replace every 10,000 miles.
⚠️ Signs your fuel filter is due:
- Hard starting or extended cranking
- Loss of power under load or while towing
- "Water in Fuel" warning light on your dash
- Rough idle or stumbling at highway speeds
- Decreased fuel economy
Installation Overview
The fuel filter housing is located on the driver-side frame rail, just behind the front wheel. No lift required — most DIYers complete this in 15–20 minutes with basic hand tools.
Tools needed: 28mm socket or fuel filter cap wrench, flathead screwdriver, drain pan, clean rags.

Frequently Asked Questions
Q: Is this a genuine Mopar filter?
A: This is an iFJF aftermarket filter manufactured to meet or exceed Mopar OEM specifications. We supply the same IATF 16949-certified production lines that many major filter brands use.
Q: Will this fit my 2018 Ram 3500 dually?
A: Yes. This filter fits all 2013–2018 Ram 2500, 3500, 4500, and 5500 trucks with the 6.7L Cummins turbo diesel engine — SRW and DRW.
Q: Does the filter come with the O-ring?
A: Yes. The kit includes the fuel filter element, water separator, and all required O-ring seals.
Q: How often should I drain the water separator?
A: Drain the water separator every oil change (or monthly). Open the drain valve on the bottom of the housing and let it run until clear diesel appears. If the "Water in Fuel" light comes on, drain immediately.
Q: Will this void my warranty?
A: No. Under the Magnuson-Moss Warranty Act, using an aftermarket filter cannot void your factory warranty unless the filter itself caused the failure — and our filters are built to OEM spec.
