Elec. Fuel Pump

The electric fuel pump (MAL29259) is a high-performance in-line injection unit designed for carbureted and fuel-injected engines that demand reliable, consistent fuel delivery at moderate pressures. Built as part of the Comp Pump Series 140 line, this 12-volt electric fuel pump is engineered for street performance, restorations, and vintage car enthusiasts who need to replace worn mechanical pumps or convert to electric fuel delivery. Whether you're upgrading a classic engine or modernizing fuel system reliability, this pump delivers the flow and pressure balance needed for engines running naturally aspirated or lightly modified configurations.

This electric fuel pump operates at 120 gallons per hour (gph) flow rate while maintaining a steady 6 pounds per square inch (psi) pressure, optimized for 12-volt electrical systems common to most American and import vehicles. The in-line design integrates seamlessly into fuel lines without requiring tank submersion, simplifying installation on retrofit projects and older platforms where internal tank pumps are difficult to access. Female NPT 3/8-inch inlet and outlet ports provide industry-standard fuel line connectivity, while the pump's compact form factor—weighing just 4.45 pounds with dimensions of 6.6 x 4 x 9.8 inches—allows flexible mounting in engine bays, frames, or under-vehicle locations. The gasoline-compatible construction ensures longevity and corrosion resistance in typical fuel system environments.

Mechanics and restorers benefit most from this pump when converting carbureted engines to modern reliability standards or replacing failed original equipment on pre-1980s vehicles where mechanical pump failures are common. The 6 psi delivery is ideal for carburetor and low-pressure fuel-injection systems; however, confirm your engine's fuel pressure requirement before installation, as high-pressure direct-injection systems demand specialized regulators or higher-capacity pumps. Mount the pump in-line between the fuel tank and carburetor or fuel rail using standard hose barbs or NPT adapters, incorporating a fuel filter upstream and a pressure regulator downstream to protect downstream components and maintain precise delivery. This electric unit eliminates fuel starvation on sustained high-load driving and provides consistent cold-start performance that mechanical pumps often struggle to deliver.
