Add to Cart
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 ½” 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.
