FASS FASC09250G ADJUSTABLE DIESEL FUEL LIFT PUMP 250G FOR 2001-2016 GM DURAMAX 6.6L LB7/LLY/LBZ/LMM/LML

The FASS FASC09250G Adjustable Diesel Fuel Lift Pump 250G for 2001-2016 GM Duramax 6.6L LB7/LLY/LBZ/LMM/LML is a cutting-edge addition to the range of FASS Fuel Systems. Engineered as part of the Signature Series, this fuel system is meticulously crafted to offer unparalleled performance ideal for GM Duramax 6.6L engines looking to maximize power and efficiency.

Crafted with precision using top-grade materials, including the same motor utilized in the Titanium Signature Series Systems, this adjustable fuel pump is optimized to deliver an impressive 250 gallons of diesel fuel per hour. What sets this system apart is its ability to adjust fuel pressure between 1-75 PSI, catering to the specific requirements of high-performance race or competition diesel engines.

Enhancing its functionality, a boost compensation port is integrated to ensure that air pressure from the intake manifold boosts fuel pressures during heavy throttle use, maintaining consistent fuel pressure when it matters most. The kit comes complete with a bulkhead fitting and suction tube, further streamlining the installation process.

Constructed from high-quality 6061 T-6 Billet Aluminum, the bulkhead fitting doubles as a suction tube and return, featuring a 5/8 inch Suction Tube and a 1/2 inch Fuel Return Port. The updated suction tube design enables users to connect their FASS return line directly to the bulkhead fitting, eliminating the need for modifying the filler neck and significantly expediting installation.

Notable features of the Duramax Adjustable High-Performance System include Whisper Technology for quiet operation, improved fuel flow, a built-in fuel pressure gauge port for easy monitoring, and all necessary mounting hardware for seamless installation. It's important to note that this fuel system should be used alongside the factory fuel filter, and adjustments are recommended only with the installation of a fuel pressure gauge for precise tuning and performance enhancement.
