ProStar 500 Electric Fuel Pump

The ProStar 500 Electric Fuel Pump by MAGNAFUEL/MAGNAFLOW FUEL SYSTEMS is a dedicated in-line electric fuel delivery solution designed for high-performance automotive applications requiring reliable, consistent fuel pressure. Built for both gasoline and E85 fuel compatibility, this 500 series pump serves street performance, racing, and fuel system retrofit projects where OEM pumps fall short. The pump's compact, inline design makes it ideal for custom fuel system installations where space efficiency and dependable operation are non-negotiable.

This electric pump delivers 25–36 psi operating range, making it suitable for naturally aspirated and moderately boosted engine applications requiring stable fuel delivery without excessive pressure spikes. The pump features 12 AN female O-ring inlet and outlet ports, ensuring secure, leak-free connections to high-flow fuel lines, while an integral 8 AN bypass circuit protects against over-pressurization and extends pump longevity. The dual-fuel capability—rated for both gasoline and ethanol blends—eliminates the need for multiple pumps in flex-fuel or alternative-fuel engine builds, and the in-line mounting orientation allows flexible installation within fuel tanks or external mounting scenarios.

Street enthusiasts, drag racers, and fuel system designers benefit most from the ProStar 500's combination of pressure precision and fuel compatibility. Engine builders integrating modern fuel injection systems, turbocharger setups, or converting to alternative fuels will find this pump's bypass regulation critical for maintaining optimal fuel rail pressure and preventing injector damage. Installation requires proper wiring to a 12-volt source with appropriate relay protection; the compact 8.3 x 4.8 x 8.4 inch footprint (7.07 lbs) permits mounting in fuel tanks or engine bays with minimal space constraints. For comprehensive fuel system upgrades or OEM pump replacement on performance vehicles, verify fuel line sizing and pressure regulator compatibility before final assembly.
