Description

It allows for adjustable fuel pressures between 1-20 PSI, catering to the demands of race or competition applications. This pump utilizes the same motor found in FASS's Titanium Signature Series, delivering a robust 165 gallons of diesel fuel per hour. Key features include a boost compensation port, which uses intake manifold air pressure to increase fuel pressure during full throttle operation, ensuring consistent fuel delivery when it's most critical. The pump is constructed from 6061 T-6 Billet Aluminum for durability and includes the FASS STK-1002 Bulkhead and Suction Tube Kit. This improved kit allows for direct plumbing of the FASS return line to the bulkhead fitting, eliminating the need to cut the filler neck and speeding up installation. The PTFE Teflon pickup tube can be cut to suit various fuel tank depths, allowing operation down to approximately 1/8 tank. This product is specifically designed for 2010-2014 Dodge Ram 2500 and 3500 models equipped with the 6.7L Cummins engine. It is a fuel pump only and requires the use of the factory fuel filter. It is recommended that users install a fuel pressure gauge before adjusting the pump's pressure settings.
