Product Description
Take command of your fuel delivery with the FLEECE FPE-FFD-RF-3G — a precision-machined fuel distribution block designed for 2003–2007 3rd gen Dodge Ram trucks equipped with the 5.9 L Cummins diesel engine. Built to streamline high-flow systems, this block eliminates the factory fuel filter and offers dedicated ports for feeds, returns and sensors — ideal for dual CP3 pump setups, filtration upgrades and serious performance diesel builds.
Why the Fleece Fuel Distribution Block?

- Cleans up engine bay layout and simplifies fuel system plumbing when upgrading to aftermarket filtration or dual CP3 pumps.
- Trusted brand with one-year limited parts warranty.
