Electric Fuel Pump 4-8 PSI

The Carter Electric Fuel Pump 4-8 PSI (Model P4070) is a compact, in-line electric fuel pump engineered for classic and modified vehicles that require low-pressure fuel delivery without the complexity of carburetor-fed mechanical pumps. This pump is ideal for hot rodders, classic car enthusiasts, and DIY mechanics restoring pre-1980s vehicles or building carbureted performance engines where reliable, consistent fuel flow at modest pressure is critical for engine idle quality and response.

Built with proven Carter engineering, this electric fuel pump delivers 72 gallons per hour at its rated 4–8 PSI operating window, making it suitable for naturally aspirated carburetor applications and low-boost fuel systems. The pump features a 3/8-inch hose barb inlet and outlet fitting, allowing straightforward integration into existing fuel lines without adapter complexity. Its compact form factor (4.5 x 3.8 x 7.7 inches, weighing 3.6 lbs) fits easily into engine bays, under rear seats, or inline fuel system installations, while the included mounting bracket and hardware streamline installation and reduce vibration transfer to the vehicle chassis.

Mechanics and restorers benefit most from this pump when converting mechanical fuel systems to electric delivery, eliminating camshaft-driven fuel pump wear and enabling fuel cell installations. It pairs well with carbureted street engines, vintage truck restorations, and specialty fuel systems where low pressure is a requirement—high-pressure fuel injection systems demand alternative solutions. Proper fuel line sizing, a quality fuel filter upstream, and inline pressure regulator installation ensure longevity and consistent carburetor float bowl fill rates across engine operating ranges.
