Electric Fuel Pump - Street

The Holley Electric Fuel Pump – Street (SKU HLY12-801-1) is a modern, reliable solution for custom fuel delivery in street-driven vehicles and engine swaps where factory carbureted systems no longer apply. As a mechanic, you know that transitioning from mechanical to electric fuel delivery eliminates the complexity of carburetor-fed pressure fluctuations and allows precise control over fuel delivery across idle, cruise, and wide-open throttle conditions. This in-line electric pump is purpose-built for naturally aspirated and lightly boosted engines that demand consistent flow without the bulk and maintenance of traditional mechanical pumps.

Built with Holley's reputation for quality, this electric fuel pump delivers 71 gallons per hour (gph) at 4 psi—a flow rate and pressure sweet spot for carburetor and returnless EFI applications on street engines. The pump features 3/8-inch NPT female inlet and outlet ports, allowing straightforward integration into existing fuel lines with standard fittings; the silver finish housing resists corrosion, while the in-line design minimizes installation footprint in tight engine bays. At just 3.26 lbs and compact dimensions (5.75 x 4.15 x 6.95 inches), it mounts easily under the car or inside the fuel tank without significant structural modification, and its gasoline-compatible construction ensures long service life when paired with quality fuel filters.

Street enthusiasts, restorers, and engine builders benefit most from this pump when upgrading carbureted vehicles to modern reliability or installing crate engines in custom chassis. It pairs seamlessly with Holley carburetors and single-plane manifold setups, and its 4 psi output suits naturally aspirated combinations where boost-fed delivery isn't required. Installation is straightforward: mount the pump between the tank and carburetor, wire it to a relay on your ignition circuit, and equip your fuel line with an appropriate bypass regulator to fine-tune pressure for your specific carb or EFI tune. For any street-driven build seeking dependable electric fuel delivery without over-engineering, this Holley pump delivers.
