Enhance fuel filtration efficiency and serviceability in your 2007.5-2009 Dodge 6.7L Diesel with the XDP Fuel Filter Adapter With CAT 1R-0750 Filter XD391. The XDP Cat Filter Adapter features a CNC-machined, billet aluminum filter head that is designed to replace the stock filter assembly. The new filter head is designed to accept the CAT 1R-0750 advanced high efficiency fuel filter to provide your engine with superior filtration and protection. The XD391 features a bolt-on installation by mounting the new fuel filter head in place of the factory housing. Removing the factory housing helps reduce maintenance costs, while also eliminating common issues like cracking, leaks, or seizing with the plastic filter canister design. Each kit comes ready to install with filter head, CAT 1R-0750 fuel filter, fuel filter delete (for factory low-pressure lines) and the necessary hardware for installation.

quality parts, no instructions though
Really high quality fittings and pretty easy to put together once you figure out where everything threads into. Just takes a little bit to figure out where everything goes and I wish it came with instructions. No instructions is the only reason for 4 stars.

Aftermarket fuel filter assembly
I was very impressed with the quality of the product and speed of delivery on the aftermarket fuel filter assembly I ordered. I do wish they included some basic instruction on the assembly though I'm sure it will be fairly straightforward. The lack of instructions is the only reason I gave it 4 stars instead of 5.

Questions and Answers

Does this cut out the WIF sensor or does it have a port for it still?
View Staff Answer 
The XDP 6.7L CAT Filter Adapter XD391 will retain the WIF sensor but it will remove the factory heating element.
