Upgrade your fuel system with this fuel filter delete from Fleece Performance Engineering. If you have an aftermarket fuel filtration system such as an Air Dog or a FASS, your factory fuel filter is no longer necessary. The factory fuel filter only becomes an extra restriction and an eye sore. This fuel filter delete will remove that restriction and help clean up under the hood of your truck. It mounts perfectly to allow the factory fuel return lines to be used without any relocating or bending. It also features a port for the factory WIF (water in fuel) sensor and a 9/16-18 O-ring port for a dual CP3 return line.
