Take Control Of Your Duramax Fuel System Like Never Before

If you are building a serious 2001-2016 6.6L Duramax and want full control over fuel delivery, this FASS 290GPH Adjustable Fuel Lift Pump gives you the flexibility most systems simply cannot. Rated at 290 gallons per hour, it is designed to support high horsepower street trucks and competition setups that demand consistent fuel volume. What really makes this pump stand out is the adjustable pressure range from 1 to 75 PSI, allowing you to fine tune your setup based on your injectors, turbo configuration, and tuning goals. That kind of control can make a real difference when you are chasing clean power and stable rail pressure under load. Additionally, the built in boost compensation port raises fuel pressure as boost increases, helping maintain supply when you are deep into the throttle. Instead of watching pressure fall off at the top of a pull, you get the confidence that your fuel system is keeping up. For Duramax owners who want performance without compromise, this pump delivers the flow and adjustability to back up serious power.

Engineered For High Flow Stability And Clean Installation

Under the hood, this Signature Series adjustable pump uses the same proven motor found in the Titanium Signature line, giving it the durability to handle demanding diesel applications. It is designed to work with your factory fuel filter, simplifying the overall system while still delivering the volume required for modified trucks. The included STK-1002 bulkhead and suction tube kit is machined from 6061 T-6 billet aluminum and functions as both a suction and return point. With a 5/8 inch suction tube and 1/2 inch return port, the system supports strong fuel draw and efficient return flow. Furthermore, the PTFE Teflon pickup tube can be trimmed to match different tank depths, which helps streamline installation across various configurations. The updated bulkhead design eliminates the need to cut the filler neck, saving time and reducing installation headaches. When properly installed, the system can safely operate down to about 1/8 tank of fuel, giving you reliable performance without constantly worrying about running the tank too low.
