Upgrade your fuel system with this fuel distribution block from Fleece Performance Engineering for the 2003–2009 common rail Cummins. If you are running an aftermarket fuel filtration system such as an AirDog or FASS along with dual CP3 pumps, this block eliminates the unnecessary factory fuel filter and gives you a clean, centralized location to route your feeds, returns, and sensors.

Mounts directly in the factory fuel filter location — no relocating or bending of factory return lines required. Features a port for the factory WIF (Water in Fuel) sensor so your dash warning system remains fully functional. Built to support dual CP3 configurations with dedicated feed, return, and sensor ports throughout.

Port configuration: WIF sensor port, one 9/16-18 O-ring port for dual CP3 return (with -6AN male fitting included), three 3/4-16 O-ring ports for feeds (with -8AN male fittings included), and two 1/8-inch NPT sensor ports.
