EFI Electric Fuel Pump

The EFI Electric Fuel Pump by AEROMOTIVE (MPN 11103) is a high-performance fuel delivery system engineered for modern fuel-injected engines requiring precise, consistent fuel pressure. Whether you're building a stroker, converting a carbureted classic to EFI, or upgrading an aging stock fuel system, this electric pump eliminates the reliability issues inherent in mechanical fuel pumps and vacuum-operated designs. Weighing just 3.55 lbs with compact dimensions of 5 x 4.1 x 8.8 inches, this pump integrates seamlessly into engine bays with tight clearance constraints or custom fuel cell installations.

AEROMOTIVE's electric fuel pump design prioritizes flow stability and pressure regulation across the RPM range your engine demands. Electric pumps outperform mechanical alternatives by maintaining consistent fuel delivery regardless of engine load or temperature fluctuations—critical when tuning fuel injection systems for maximum efficiency and power output. The compact form factor allows mounting in-tank, in-line within fuel rails, or remotely in fuel cell assemblies, giving fabricators flexibility in system layout. Coupled with a quality fuel pressure regulator and proper gauge installation, this pump enables repeatable baseline pressure (typically 43.5–50 PSI for direct-injection EFI systems) essential for datalogging tuning sessions and diagnosing fuel delivery faults.

Mechanics and engine builders favor AEROMOTIVE electric fuel pumps when retrofitting EFI onto carbureted platforms, where OEM mechanical pumps cannot sustain the flow and pressure EFI injectors require. This pump is ideal for naturally aspirated and boosted applications—turbo and supercharged builds benefit from stable, ripple-free fuel delivery under sustained boost. Verify your fuel line sizing (typically -6 or -8 AN) and confirm pump voltage compatibility with your vehicle's electrical system (most AEROMOTIVE pumps operate on 12V) before installation. Pair with an appropriate fuel filter, check valve, and pressure relief valve to complete a robust fuel system capable of supporting bolt-on modifications, full engine builds, and long-term reliability.
