FASS FASD07165G Signature Series Adjustable Diesel Fuel Lift Pump - 165GPH

The FASS FASD07165G is a Signature Series Adjustable Diesel Fuel System rated at 165 gallons per hour (GPH), engineered for high-performance Dodge Cummins 5.9L and 6.7L diesel applications. Built with the same motor platform used in the FASS Titanium Signature Series, this adjustable diesel fuel lift pump delivers the fuel volume needed to support moderate to extreme horsepower builds in the 600–900 HP range.

Fuel pressure is fully adjustable from 1–20 PSI, allowing precise tuning to match the demands of race or competition diesel engines. A built-in boost compensation port uses air pressure from the intake manifold to automatically raise fuel pressure under full throttle, ensuring consistent fuel delivery when it matters most. An integrated fuel pressure gauge port makes monitoring straightforward.

The kit includes a FASS STK-1002 Bulkhead and Suction Tube Kit. The bulkhead fitting is machined from 6061 T-6 billet aluminum and serves as both the suction tube and return fitting, featuring a 5/8" suction tube and a 1/2" fuel return port. This design eliminates the need to cut the filler neck, significantly simplifying installation. The PTFE Teflon pickup tube can be trimmed to fit varying fuel tank depths, and the system is designed to operate reliably down to approximately 1/8 tank of fuel.
