The XDP Fuel Tank Sump One Hole Design with Built-In Fuel Return is easier to install than others on the market, it only requires one hole! The fuel tank sump provides an outlet for fuel on the bottom of your tank which eliminates the typical 1/4 tank issues associated with in-tank straws used with aftermarket fuel systems. The inner ring is designed to fit in the bottom of the tank without needing to remove it from the truck. A machined groove for the o-ring gasket ensures a leak free seal and the 2 bolt design eliminates the need to drill additional bolt holes in your tank. For use with aftermarket systems, includes 1/2 NPT fitting for 1/2" hose.

The XDP special polished edition features a highly polished design to add a custom look under your truck. The built-in return also makes it easier to install an aftermarket fuel system that requires you to cut into the factory fuel filter neck. For optimal fuel quality this sump features a stand pipe that places the returned fuel above the fuel feed which helps eliminate the possibility of giving your engine the aerated return fuel coming back to your tank.
