The Smashed Performance Fuel Tank Sump with Built-In Return provides you with a perfect option to maximize fuel delivery, and customization when installing your aftermarket fuel system. Our kit features a one-hole design that only requires drilling a single 3″ hole for installation. Two machined grooves allow for two o-ring gaskets to ensure a leak-free seal. Our sump is also secured to a top plate with two bolts (with sealing washers) for a strong secure seal. The notches on the top plate allow for the sump to be installed without the need of dropping your fuel tank.
