The XDP Fuel Tank Sump with Built-In Fuel Return XD243 provides you with a perfect option to maximize fuel delivery, and customization when installing your aftermarket fuel system. Avoid the common 1/4 tank issues associated with in-tank draw straws used with fuel systems such as AirDog, FASS and many others. The XD243 features a one-hole design that only requires drilling a single 3" hole for installation. A machined groove for the o-ring gasket ensures a leak-free seal, and the inner-ring is designed to fit into the bottom of the tank without requiring you to remove it from the truck. What sets the XD243 apart from the other sumps in the XDP lineup is the built-in return. Installation of most aftermarket fuel systems require you to cut and "tee" into your factory fuel filler neck. In some cases, modifications to the filler neck can cause leaks, and also cause fuel pumps to "click off" when refueling. Using the built-in return port, you can easily route return fuel back to the tank without having to modify any other components for a clean and easy installation. For optimal fuel quality, the XDP Sump features a stand pipe that places the returned fuel above the fuel feed. This design eliminates the possibility of feeding your engine the aerated return fuel coming back to your fuel tank. Includes barbed fittings for 1/2" hose.

Note: Not recommended for off-road applications or for vehicles with potential ground clearance issues. Extra care must be taken to ensure that fuel tank is free of debris after drilling.
