High-Quality Fuel Sump Kit for FASS Fuel Systems

If you've ever dealt with fuel starvation around a quarter tank—especially when towing, accelerating hard, or running your truck near empty—you know how frustrating it can be. The FASS Feed/Return Style Sump Kit solves that problem for good. Designed for universal use across diesel platforms like Cummins, Duramax, and Powerstroke, this sump kit offers a cleaner, more efficient way to draw and return fuel, all without the need to drop your tank. What makes this kit especially user-friendly is its single-bolt mounting system. Instead of wrestling with multiple bolts or time-consuming brackets, all it takes is one hole and one fastener. That means less time under the truck and more time doing what matters—getting it back on the road. Once installed, the sump pulls fuel from the lowest point in the tank, giving your system consistent, uninterrupted flow, even when you're down to the last few gallons. No more fuel starvation when you're climbing steep grades or braking hard with a heavy load behind you.

Complete Kit with High-Quality Hardware

This kit also features 1/2-inch NPT ports for both suction and return, making it ideal for high-volume fuel systems like the FASS Titanium Signature Series. The built-in extra-large fuel bowl acts like a reservoir, maintaining steady fuel supply during rapid throttle changes or low-tank situations. It's a small addition that plays a big role in maintaining performance and drivability under stress. Durability is another strong point. The entire sump is machined from 6061 billet aluminum, offering solid strength and resistance to corrosion over time. Whether you're upgrading for performance, reliability, or ease of install, this kit checks all the boxes.

Important Note: This product is suggested to be installed with the FASS Titanium Signature Series Systems. The larger suction tubes and Fuel Sump Bowl improve fuel delivery and work perfectly with a higher volume fuel Systems.
