ProStar 500 Electric Fuel Pump w/Filter

The ProStar 500 Electric Fuel Pump with Filter from Magnafuel/Magnaflow Fuel Systems is a dedicated in-line fuel pump engineered for street performance and racing applications. This black electric fuel pump delivers consistent 25–36 PSI output, making it ideal for carbureted and fuel-injected engine builds requiring precise fuel delivery without oversupply. The integrated fuel filter eliminates the need for a separate component, streamlining installation and reducing plumbing complexity on custom and restoration projects.

Specifications are designed for versatility across fuel types. The pump features 12 AN female O-ring inlet and outlet ports for robust high-flow connections, paired with an 8 AN bypass circuit that regulates excess pressure and protects sensitive fuel system components. This configuration supports both gasoline and E85 ethanol blend operation, allowing tuners to transition between fuel types without pump replacement. The integrated filter captures particulate matter upstream, extending carburetor needle-and-seat life and fuel injector service intervals.

This pump suits builders transitioning from mechanical to electric fuel delivery, owners upgrading carbureted engines to higher flow demands, and racers standardizing their fuel system architecture. The compact form factor and integrated filter housing fit tight engine bays and custom mounting scenarios. Whether supporting a rebuilt 500+ horsepower carb setup or a modern EFI conversion, the ProStar 500 provides the pressure consistency needed for reliable part-throttle response and full-throttle power delivery.

In the market for an electric fuel pump with built-in filtration, the ProStar 500 represents a practical all-in-one solution that reduces leak points and component count while maintaining the 25–36 PSI sweet spot preferred by traditional fuel system designers and modern performance tuners alike.
