Description
Overview
The FASS Adjustable Diesel Fuel Lift Pump 165GPH is built for Ford Powerstroke 6.4L trucks and SUVs from 2008-2010 that demand serious, tunable fuel delivery. Engineered by FASS Fuel Systems as part of their ADJ Fuel System Series, this Signature Series lift pump uses the same motor found in FASS Titanium Signature Series systems, giving it the durability and flow characteristics of a top-tier fuel system while allowing you to dial in pressure to match your specific power goals.
Rated for a robust 165 gallons per hour, this fuel system is purpose-built for Moderate to Extreme applications in the 600-900 HP range, making it a strong match for performance-minded 6.4L Powerstroke owners who need consistent fuel supply under demanding conditions. Fuel pressure is adjustable from 8-10 PSI out of the box, giving you the flexibility to fine-tune delivery to your engine’s specific requirements rather than being locked into a fixed-pressure setup.
Key Benefits
Adjustability is the core advantage of this system. Instead of a one-size-fits-all lift pump, the ADJ Fuel System Series lets you customize fuel pressure to suit your build, whether you’re running moderate upgrades or pushing toward the extreme end of the performance spectrum. A built-in boost compensation port uses air pressure from the intake manifold to raise fuel pressure under full throttle, helping maintain proper fuel delivery exactly when your engine needs it most. A dedicated fuel pressure gauge port is also built in, so you can monitor system performance directly without improvising a tap point.
The pump housing is machined from 6061 T-6 billet aluminum and finished in black, giving it the strength and heat resistance needed for demanding diesel fuel system duty. Everything required for installation is included in the kit, and all mounting hardware ships with the unit to simplify the install process.
Fitment
This FASS Adjustable Diesel Fuel Lift Pump is designed specifically for 2008-2010 Ford Powerstroke 6.4L trucks and SUVs. It is sold as a complete fuel system kit and is intended to be used in conjunction with your factory fuel system components as part of a properly configured setup.
