FASS Fuel Systems Signature Series Adjustable Diesel Fuel System 250GPH GM Duramax 6.6L 2001-2016 (FASC09250G)

Part No: FAS C09 25G Our FASS 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 GM Duramax 6.6L applications.

Manufactured with the same motor used in our Titanium Signature Series Systems, this adjustable fuel System is rated at 250 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 fitting 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 inch Suction Tube along with a 1/2 inch Fuel Return Port. This new and improved version from 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 speeds up the installation process.

The pickup tube is fabricated of PTFE Teflon which can be easily cut to adapt to different depth of fuel tanks. Properly installed, you can safely operate down to about 1/8 tank of fuel.

Duramax Adjustable High Performance System Features:

  • Whisper Technology
  • Adjustable Fuel Pressure 1-75 PSI
  • High Performance 250GPH
  • Includes bulkhead and suction tube
  • Improves Fuel Flow
  • Boost Compensation Port
  • Built In Fuel Pressure Gauge Port
  • All Mounting Hardware Included

This is a fuel System only and must be used with your factory fuel filter. It is suggested that all Systems be adjusted only if you have installed a fuel pressure gauge.
