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.

Fantastic product
(Baltic, CT) | June 15th, 2020
So IWas running my airdog threw my factory draw straw for a while and finally got sick of the 1/4 tank issue and decided to throw this sump in it. I didn’t remove the tank and it was relatively easy to install with the tank in the truck. Ounce I re filled the tank I instantly noticed a performance difference in the truck. I highly recommend using this sump! Order # 1174016
