ProStar 500 Pump

The MagnaFuel fuel pump part# MP-4401 is designed for vehicles NOT subject to emission controls. The PRO STAR 500 series can be run continuously up to 1-1/2 hours for limited street driving. The MP-4401 is a precision assembly for maximum performance.

This pump, like all MagnaFuel pumps, is compatible with all racing gasolines and alcohol
fuels. Fuel additives are not recommended and may void the warranty. The MP-4401 has an external by-pass that is adjustable from 25 to 35 psi. They come preset at 28 psi. The PRO STAR 500 Series has enough flow capacity to support 2000 HP on gasoline or 1200 HP on alcohol. All MagnaFuel pumps require a #8 return line and a #8 vent or rollover valve. Return line and vent must be above the fuel level. The Pro Star 500 series pump is designed to work with a dead-head style regulator, if a by-pass style regulator is desired; the by-pass at the
pump must be capped or plugged.
