Fuel Tank Sump With Integrated Return


Cummins Duramax and Powerstroke applications

Fuel Tank Sump with Built-In Fuel Return 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 along with many others.

The sump features a one-hole design that only requires drilling a single 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. We even include a 3″ hole saw for drilling your tank. It makes the installation a breeze.

What sets this sump apart from the other sumps in our 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 Sump features a standpipe 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.

Neck & Shoulder pain gone
I absolutely love this pillow! I was experiencing horrible neck & shoulder pain with other pillows. So I was desperate to find a side sleeper pillow that was give me relief. After just a few nights in this pillow I had much less pain. A week later and no pain!
