FASS Fuel Systems Adjustable Diesel Fuel System 165GPH GM Duramax 6.6L 2001-2016 (FASC09165G) Part No: FASC09165G

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 165 gallons of diesel fuel per hour and offers adjustable fuel pressure from 1-20 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.

Duramax Adjustable High Performance System Features:

  • Whisper Technology
  • Adjustable Fuel Pressure 1-20 PSI
  • High Performance 165GPH
  • 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.
