Our FASS Fuel Systems Signature Series Adjustable Diesel Fuel Systems are designed to be the most versatile high-performance fuel System on the market that allows for adjustable fuel pressures to meet the demand of high-performance Ford Powerstroke 6.7L applications. Manufactured with the same motor used in our Titanium Series Systems, this adjustable fuel System is rated at 240 gallons of diesel fuel per hour and offers adjustable fuel pressure from 1-75 PSI to customize fuel delivery for race or competition diesel engines. To aid in proper performance we built in a boost compensation port, air pressure from your intake manifold raises fuel pressures while under full throttle, maintaining fuel pressure when it matters most.

This kit includes a Bulkhead and Suction Tube. Machined from 6061 T-6 Billet Aluminum, the Bulkhead fitting functions as both a suction tube and return and features a 5/8″ Suction Tube along with a 1/2″ Fuel Return Port. This new and improved version of our previous Suction Tube allows the user to plum their FASS return line directly to their bulkhead fitting, eliminating all cutting of the filler neck and significantly speeding up the installation process. The pickup tube is fabricated of PTFE Teflon which can be easily cut to adapt to different depths of fuel tanks. Properly installed, you can safely operate down to about 1/8 tank of fuel.
