The XDP Fuel Tank Sump is designed to eliminate the typical ¼ tank issues associated with the in-tank draw straws typically used with aftermarket fuel systems such as Air Dog and FASS pumps. Designed for better diesel fuel delivery, the XDP Fuel Tank Sump fastens to the bottom of your fuel tank and dramatically increases volume to the fuel pump by allowing you to get every drop of fuel out of your tank. The XDP Fuel Sump is the first sump on the market to feature a single piece horseshoe shaped internal ring allowing for a no tank drop installation. This exclusive feature allows for a faster and easier installation.

To provide a leak free seal, the XDP Fuel Tank Sump has been re-designed to feature (2) o-ring gaskets that install into machined grooves for a perfect fit! The XDP Fuel Tank Sump is beneficial to all trucks including stock daily drivers, mild street modifications, drag racing applications, and even sled-pulling. Includes barbed fitting for 1/2" hose.

  • Dual O-Ring Gaskets
  • No tank drop installation cuts installation time
  • Large opening for unrestricted fuel flow
  • Made from Aircraft grade T6 billet aluminum
  • Precision CNC machining technology for a perfect fit
  • Works great with stock or aftermarket fuel tanks

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.

great product
I installed this on a 6.0 powerstroke, I was having issues loosing fuel pressure when the tank would get low. I installed this kit and I haven't had any more problems with loosing fuel pressure anymore.
Makes more sense than a draw straw....
So I just bought the Fass titanium 150 and didn't want to mess around with the 1/4 tank problem so bought the xdp sump. Love it!!! Install was cake. Hardest part was dropping the tank. I dropped it to ensure no plastic shavings would get inside...which there were a lot. Have had a tank from full to almost empty and no issues whatsoever. Thanks xdp for another great product, excellent customer service and as shipping!
pay attention to torque specs
works great and looks good. i used this with my airdog 150 so i didnt need to drill the top of the tank and i think this is a way better option just be weary if you are low to the ground though it hangs pretty low. order number 895205
