Push Your Cummins Harder Without Losing Fuel Pressure

If you're running a tuned or built 2010-2014 Ram 2500 or 3500 with the 6.7L Cummins, the last thing you want is your fuel system falling behind. The FASS FASD05165G Adjustable Fuel Lift Pump keeps your engine fed and ready to deliver maximum performance, whether you're towing heavy loads or laying into it at the track. With a flow rate of 165 gallons per hour and adjustable fuel pressure from 1 to 20 PSI, this pump is built for trucks that demand more than stock. It’s designed to grow with your build, giving you the control to dial in your fuel delivery for future upgrades or high-demand setups. The built-in boost compensation port also helps keep your fuel pressure consistent when you’re deep into the throttle. That means no drops in pressure when it matters most. Installation is a breeze with the included STK-1002 Suction Tube Kit, which eliminates the need to cut into the filler neck. If you’re serious about performance and reliability, this is the pump your Cummins deserves.

Engineered For Precision Fuel Delivery And Easier Installation

The FASS Signature Series Adjustable Lift Pump is more than just a fuel pump upgrade, it’s a fully engineered solution designed for consistent fuel delivery and long-term durability. Using the same motor found in FASS’s Titanium Series, this pump delivers 165 GPH of diesel flow to support high-performance builds while giving users full control over fuel pressure from 1 to 20 PSI. A boost compensation port is integrated into the housing to help regulate pressure under full-throttle conditions, ensuring a steady flow even under heavy engine load. The included STK-1002 bulkhead and suction tube kit simplifies installation by replacing the need to cut the filler neck, making the job faster and cleaner. Machined from 6061 T-6 billet aluminum, the bulkhead fitting is both strong and corrosion-resistant, and its 5/8 inch suction tube and 1/2 inch return port are designed to move fuel efficiently. The PTFE pickup tube can be trimmed to fit a variety of tank depths, allowing safe operation down to about 1/8 tank. For trucks pushing serious power, this lift pump delivers the reliability and customization needed to stay ahead.
