Diesel enthusiasts with Dodge Cummins trucks, this Fleece Performance Engineering fuel distribution block is a serious upgrade for your fuel system! Specifically designed for 2003-2007 5.9L and 2007.5-2009 6.7L Cummins engines, it replaces your factory fuel filter when you're running aftermarket filtration systems like AirDog or FASS with dual CP3 pumps. The block mounts right in the factory fuel filter location, so you can use your existing return lines without any bending or modifications - super convenient. It's packed with ports including one for the factory WIF (water in fuel) sensor, a 9/16-18 o-ring port for dual CP3 return, three 3/4-16 o-ring ports for feed lines, and two 1/8\ NPT ports for additional sensors. The kit comes complete with everything you need - the fuel block itself, replacement banjo washers, all the necessary fittings and plugs. The quality is exactly what you'd expect from Fleece Performance - precision machined, great finishes, and built to handle the demands of performance diesel applications. Installation is straightforward if you're comfortable with fuel system work, but make sure you have the right tools and follow proper procedures. This cleanly organizes your fuel lines, eliminates the restrictive factory filter housing, and gives you a professional foundation for your upgraded fuel system. Whether you're building a tow rig, performance truck, or just want the reliability of a better fuel distribution setup, this block delivers both function and that clean engine bay look every diesel owner wants.
