The Mighty Mite fuel pumps are designed for carbureted applications for cars, trucks, generators, and agricultural equipment. They run off of a simple 2-wire 12-volt connection. The pump is self-priming, and the fuel pressure is self-regulating between 4 to 7 psi. They flow 32 gallons per hour, enough to feed a 400 horsepower engine. They are quiet, at 65db, easy to install, and work with gas, diesel, blended alcohol and E85 fuels. The pump includes a fuel filter and mounting hardware, and are made in the USA. Inlet and outlets are 5/16 inch barbed for use with standard fuel line.
