Description
Overview
The FASS Adjustable Diesel Fuel Lift Pump 250F is a Signature Series Adjustable Diesel Fuel System built for owners of the 1994-1998 Dodge Cummins 5.9L 12 Valve who demand serious, tunable fuel delivery. Engineered as one of the most versatile high-performance fuel systems available, it delivers 240 gallons per hour (240GPH) and lets you dial in adjustable fuel pressure from 1-75 PSI to precisely match the demands of your build. Rated for Super Extreme 900-1200 HP applications, this is a fuel system designed to keep pace with aggressive street, race, and competition Cummins engines.
Engineered Performance
This adjustable fuel system uses the same motor found in the premium FASS Titanium Signature Series Systems, so you get proven performance and flow. The ability to customize fuel pressure means you can tailor delivery for everything from a strong daily driver setup to a full-throttle race application. A built-in boost compensation port draws air pressure from your intake manifold to raise fuel pressures under full throttle, maintaining fuel pressure exactly when it matters most and helping your Cummins stay fed at wide-open throttle.
What’s Included
Sold as a complete kit, this fuel system includes a Bulkhead Fitting and Suction Tube. Machined from durable 6061 T-6 Billet Aluminum and finished in black, the Bulkhead Fitting functions as both a suction tube and return, featuring a 5/8-inch Suction Tube along with a 1/2-inch Fuel Return Port. This is the new and improved version of the previous FASS suction tube design, giving you upgraded draw and return capability for reliable fuel pickup.
