Performance Specifications and What They Mean

When selecting a fuel pump, understanding performance specifications is crucial. Summit Racing provides clear data on flow rates, pressure ratings, and amperage draw, allowing you to match the pump to your engine's requirements.

Flow Rate

Flow rate is measured in gallons per hour (GPH) or liters per hour (LPH). For naturally aspirated engines, a pump that delivers 255 LPH (about 67 GPH) is typically sufficient for up to 500 horsepower. For forced induction or nitrous applications, you may need 340 LPH or more. Summit Racing's high-flow mechanical pumps deliver 110 GPH, which is more than enough for most street-driven big blocks.

Pressure Rating

Fuel pressure is measured in pounds per square inch (PSI). Carbureted engines typically require 5-9 PSI, while EFI systems need 40-60 PSI or higher. Summit Racing electric fuel pumps are available with pressure ratings ranging from 6 psi for carbureted applications up to 72.5 psi for high-performance EFI systems. Their in-tank pumps are designed for EFI applications and maintain consistent pressure under load.

Amperage Draw

Amperage draw affects your vehicle's electrical system. Summit Racing electric fuel pumps draw 4 amps or less at full load, which is efficient and reduces strain on your alternator and wiring. This is particularly important for vehicles with limited electrical capacity or those running multiple accessories.
