Extra Info:

FASS Fuel Systems Signature Series 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 Dodge Cummins 5.9L applications. Manufactured with the same motor used in our Titanium Signature Series pumps, this adjustable fuel pump is rated at 100 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.

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