A2000 Electric Fuel Pump

The AEROMOTIVE A2000 Electric Fuel Pump is a carbureted-application in-line fuel pump engineered for high-flow carburetor systems and fuel-injected conversions requiring consistent pressure and volume. With a free-flow capacity of 350 gallons per hour, this electric pump delivers the fuel supply necessary for naturally aspirated and moderately boosted engines where traditional mechanical fuel pumps fall short. The pump features a chrome finish and is compatible with both gasoline and E85 fuel, making it versatile across fuel blends and octane requirements.

Designed for external bypass operation, the A2000 maintains stable fuel pressure across varying engine load conditions without flooding the carburetor or over-pressurizing the system. The pump uses AN female O-ring ports—10 AN for inlet and outlet fuel lines and 8 AN for the return circuit—allowing clean, leak-resistant connections to aftermarket fuel rails, tanks, and regulators. The 7.1-pound unit mounts externally and draws current only when the ignition system activates, reducing parasitic draw compared to mechanical pumps. E85 compatibility expands tuning options for builders targeting higher octane ratings and aggressive timing curves.

This pump is ideal for street and strip carbureted hot rods, classic muscle car restorations, and carburetor-to-fuel-injection swap projects where factory fuel system capacity is inadequate. Street rodders and engine builders typically choose 350 GPH capacity for engines up to approximately 500 horsepower naturally aspirated, providing margin above peak fuel demand. The external bypass design ensures the pump doesn't cycle continuously at idle, extending component life and reducing noise. Buyers upgrading from mechanical pumps appreciate the reliability and pressure consistency an electric pump provides across all engine speeds and ambient temperatures.
