The XDP Fuel Tank Sump - One Hole Design With Fuel Return XD243 provides you with a perfect option for custom fuel delivery with an aftermarket fuel system. 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 fuel return for an easy connection to most aftermarket fuel systems. Using the built-in return port, you can easily route return fuel back to the tank without having to modify other components of your fuel system 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 prevents the aerated return fuel from going directly into the feed. Includes barbed fittings for 1/2" hose with the threads on the ports being 1/2" NPT.

THEE Best Go-To for anything Diesel!! Order #1956527
Have had a few amazing experiences with XDP. I worked directly with Erik out of their New Jersey office who really made it happen! Put the order together with Erik over the phone and he let me know then and there where the stuff would be shipping from, and when it would ship and be arriving to me. I put a big order together with some oddball requests so it made more sense for me to do it over the phone. The smaller orders that I have done online have been seamless as well! They are very clear on when to expect it to ship out. 10 out of 10. Use them!

Feed and return XDP sump
Install was easy. Fittings allow for upgrades to larger fuel flow for different applications. Wish it included a brass fuel shutoff or ball valve for easy fuel filter changes. Went to replace the fuel filter and the tank was full. Was caught off guard and fuel was free-flowing when the filter was loosened. Pinched feed line to replace and clean.
