EFI Electric Fuel Pump

The EFI Electric Fuel Pump by AEROMOTIVE (MPN 11103) is a high-performance fuel delivery system designed for modern fuel-injected engines that require precise and consistent fuel pressure. This pump is ideal for those building stroker engines, converting carbureted classics to EFI, or upgrading older fuel systems. It addresses the reliability issues often found in mechanical fuel pumps and vacuum-operated designs.

Weighing 3.55 lbs and featuring compact dimensions of 5 x 4.1 x 8.8 inches, this electric pump is designed for easy integration into engine bays with limited space or for custom fuel cell installations. AEROMOTIVE's design focuses on maintaining flow stability and pressure regulation across the RPM range, ensuring consistent fuel delivery regardless of engine load or temperature changes. This is crucial for tuning fuel injection systems to achieve maximum efficiency and power output.

Mechanics and engine builders prefer AEROMOTIVE electric fuel pumps for retrofitting EFI onto carbureted platforms due to their reliability and performance. The pump can be mounted in-tank, in-line, or remotely in fuel cell assemblies, providing flexibility in system layout. When paired with a quality fuel pressure regulator and gauge, this pump supports maintaining a baseline pressure typically around 43.5–50 PSI, essential for effective tuning and diagnosing fuel delivery issues.
