Upgrade your fuel system with this fuel distribution block from Fleece Performance Engineering. If you have an aftermarket fuel filtration system such as an Air Dog or a FASS and dual CP3 pumps, this fuel distribution block will allow you to get rid of your unnecessary factory fuel filter and give you a convenient and clean location to route your feeds, returns, and sensors. It mounts in the factory fuel filter location to allow you to use your factory return lines without any relocating or bending. It also features a port for the factory WIF (water in fuel) sensor, a 9/16-18 o-ring port (dual CP3 return port), (3) 3/4-16 o-ring ports (feed ports), and (2) 1/8" NPT ports (sensor ports).
