Our FASS Adjustable Diesel Fuel Pumps are designed to be the most versatile high-performance fuel pump 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 Series pumps, this adjustable fuel pump is rated at 165 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.
