The HOLLEY Electric Fuel Pump 25GPH Mighty Mite Series is a compact, reliable electric fuel pump designed for street rods, classic restorations, and custom fuel system builds where space and weight are critical considerations. This pump delivers a steady 25 gallons per hour—sufficient for naturally aspirated small-block and mid-displacement engines—making it an ideal choice for low-pressure carburetor applications and fuel-injected systems operating below 15 PSI. Whether you're converting a mechanical fuel system to electric power or building a modern fuel delivery setup in a vintage chassis, the Mighty Mite delivers dependable performance without the bulk of larger industrial pumps.
Engineered by HOLLEY—a leader in fuel system technology—this electric pump features a sealed, brushless motor design that runs quietly and efficiently on 12-volt DC power. The 1/8 inch NPT female inlet and outlet ports allow flexible installation in tight engine bays and accommodate standard fuel line adapters. Its black finish resists corrosion, while the compact 5.15 x 3.7 x 5.8-inch footprint and lightweight 1.04-pound construction minimize installation complexity and vehicle weight penalty. The pump operates smoothly on both gasoline and diesel fuel, providing versatility across multiple fuel types without performance degradation.
Hobbyists restoring classic vehicles and performance builders standardly choose the Mighty Mite when factory fuel system conversions or custom fuel cell setups demand a proven, space-saving solution. Mounting near the fuel tank or in the engine bay is straightforward due to its compact size and NPT threaded ports. Ensure your fuel system regulator is set to 5–15 PSI for optimal pump longevity and engine performance; this pump is not rated for high-pressure direct-injection applications. Proper wiring to a fuel pump relay and 12-volt power source, along with quality fuel line and filters, complete a professional installation that will provide years of reliable service.
