Thoroughbred Sku #: FAS8993DGADJWPUMP
Product Name: 1989-1993 Dodge Fass Adjustable Whisper Fuel Pump Manufacturer: FASS Thoroughbred Diesel Part #: FAS8993DGADJWPUMP Fitment Notes: 1989-1993 Dodge Cummins
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 applications. Manufactured with the same motor used in our Titanium Signature Series pumps, this adjustable fuel pump is rated at up to 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.
This kit includes a FASS STK-1002 (Bulkhead and Suction Tube Kit). 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 from our previous Suction Tube Kit 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.
