This high-quality affordable fuel tank sump kit solves 1/4 tank low issues and feeds the biggest performance pumps. This is exactly what you want to quiet down your high flow lift pump because a draw straw will starve your pump! Use one for your Airdog or FASS for Cummins, Duramax or Powerstroke. Only sump out there that features an interchangeable barb design. Both 1/2" and 5/8" are included. This is the only sump ready to go out of the box to run either an AirDog pump with the standard 1/2" hose ID or a higher flow FASS pump with a larger 5/8" hose ID. Will work on any flat surface gas or diesel tanks. Easy 3-bolt installation. New 3-Bolt design equally distributes clamping force around the O-ring for reduced slippage and leaks that occur with 1-Bolt designs while still being easier to install than old style sumps. You get the best of both worlds. These are conveniently shipped pre-assembled. Just cut hole and install.

Kit includes a CNC machined housing and top plate from 6061 billet aircraft aluminum in anodized black finish, stainless steel bolt, Viton sealing washer, steel drain plug, brass 1/2" NPT x 1/2" hose ID barb, 1/2" NPT x 5/8" hose ID barb, and square O-ring (Buna-N). Required installation tool is a 3-inch Hole saw. Made in Ohio, U.S.A
