Electric Fuel Pump

The Holley electric fuel pump (MPN 12-927) is a purpose-built in-line delivery system designed for carbureted and naturally aspirated fuel systems requiring consistent pressure and volume. Whether you're upgrading a classic muscle car, restoring a vintage hot rod, or building a custom engine platform, this electric fuel pump eliminates mechanical pump limitations and delivers reliable fuel supply independent of engine speed. It's engineered for builders and enthusiasts who demand dependable pressure regulation at idle, cruise, and wide-open throttle.

This in-line fuel pump features a 43 gallons-per-hour flow capacity at 15 psi, making it suitable for carbureted engines and moderate fuel-injection applications. The pump incorporates 3/8-inch hose barb inlets and outlets, standard connections that mate directly with common fuel line sizing used in street rods, classic trucks, and custom builds. The silver finish resists corrosion, and the all-gas compatible design ensures longevity in unleaded and ethanol-blend fuel environments. Electric operation means you control fuel delivery via relay and switch logic, allowing precise tuning of pump activation and pressure curves without the complexity of mechanical governors.

Mechanics and engine builders favor this Holley pump for retrofit applications where factory mechanical pumps have become unreliable or where fuel system pressure needs to remain constant across varying RPM ranges. Installation requires basic electrical and plumbing skills: mount the pump away from engine heat, run 12V power through a relay with proper amperage rating, and plumb inlet and outlet lines using the 3/8-inch barb connections. The compact footprint (5.2 x 2 x 6.8 inches) allows mounting in frame rails, fuel tanks, or engine compartments with limited space. Pair it with a quality fuel regulator and filter for optimal reliability and component protection in carbureted and light-boost applications.
