Description
The FASS Fuel Systems Signature Series Adjustable Diesel Fuel Lift Pump (Part No: FASF16250G) is purpose-built for 2008-2010 Ford Powerstroke 6.4L trucks and SUVs that demand serious, tunable fuel delivery. Rated for the Super Extreme 900-1200 HP category, this ADJ Fuel System Series pump is engineered for owners pushing their 6.4L Powerstroke into race and high-horsepower competition territory, where a fixed-pressure fuel pump simply can’t keep up.
Overview
Rated at 250 gallons per hour, this adjustable diesel fuel system uses the same motor found in FASS’s Titanium Signature Series systems, giving it the durability and flow capacity to support demanding diesel performance builds. What sets this system apart is its adjustable fuel pressure range of 1-75 PSI, allowing you to dial in exact fuel delivery to match your engine’s tuning, injectors, and horsepower goals rather than being locked into a single preset pressure.
Key Benefits
A built-in boost compensation port is a standout feature of this system. As boost pressure rises from the intake manifold under full throttle, fuel pressure is automatically increased to match, ensuring fuel delivery stays consistent exactly when your engine needs it most – under load, at high RPM, and under full acceleration. This is critical for race and high-output diesel applications where fuel starvation at the top end can cost power and risk engine safety.
Construction & Included Components
Machined from 6061 T-6 billet aluminum, the system is sold as a complete kit that includes a bulkhead and suction tube assembly. The bulkhead fitting is dual-purpose, functioning as both suction and return, and is outfitted with a 5/8 inch suction tube along with a 1/2 inch fuel return port. This updated suction tube design is an improvement over previous FASS configurations, offering better plumbing flexibility for installers.
Fitment
This adjustable fuel lift pump is designed specifically for 2008-2010 Ford Powerstroke 6.4L trucks and SUVs. Confirm your truck falls within this model year and engine range before ordering to ensure proper fit.
