Precision Parts Billet Aluminum Diesel Sump with Integrated Return For Cummins Duramax Powerstroke

The Precision Parts Billet Fuel Tank Sump with a built-in fuel return is the superior choice for optimizing fuel delivery and facilitating seamless customization when integrating your aftermarket fuel system. Say goodbye to the common 1/4 tank issues associated with in-tank draw straws used in systems like AirDog and FASS. Our billet sump boasts a one-hole design, simplifying installation with only a single hole to drill.

Crafted with precision, the Precision Parts billet sump features a machined groove for the o-ring gasket, ensuring a leak-free seal. The inner-ring is thoughtfully designed to fit snugly into the tank without necessitating removal from the truck. As part of our commitment to convenience, we even include a hole saw for effortless tank drilling!

What sets this sump apart from others in the Precision Parts lineup is its innovative built-in return. Unlike traditional aftermarket fuel systems that may require cutting and "teeing" into the factory fuel filler neck, our design eliminates this need. By utilizing the built-in return port, you can effortlessly route return fuel back to the tank without modifying other components, ensuring a clean and straightforward installation.

For superior fuel quality, the Precision Parts Sump incorporates a stand pipe that positions the returned fuel above the fuel feed. This ingenious design prevents the possibility of feeding your engine aerated return fuel, enhancing overall performance. The package includes barbed fittings for 1/2" hose, adding to the versatility of this top-tier sump.
