You can experience the advantage of a high-volume fuel system with the pump inside the fuel tank. This system can be used as a return or returnless system with the use of the built-in regulator. With the pump submerged in fuel, it will run quieter and last longer. With its multi-purpose ring and adjustable pump height, this is the easiest way to convert your existing or new fuel tank to an in-tank EFI fuel system. This system can be used in fuel tanks ranging in depth from 6” to 14.” Deeper tanks can be accommodated with an optional fuel pump extension kit.
