Product Description

The Walbro F90000285 Fuel Pump is a high-pressure universal in-tank electric pump engineered to meet the demands of high-flow performance fuel systems. Featuring an innovative dual-channel turbine impeller design, this pump delivers around **470 liters per hour (~120 GPH)** of fuel flow at typical operating pressures, providing robust supply for engines with significantly increased fuel requirements. Its design improves hot fuel flow and efficiency compared with conventional pumps, helping support smooth delivery under load in demanding driving conditions.

Compatible with both gasoline and ethanol (E85) fuels, the F90000285 incorporates a built-in check valve to help maintain system pressure during extended cranking and includes features like a high-pressure relief capability that supports turbocharged and supercharged applications. This pump suits custom and universal installations where increased fuel delivery is required - often chosen for builds capable of supporting ~900 horsepower or more when paired with appropriate regulators, wiring, and installation kits. Professional installation is recommended, including proper wiring, filters, and fuel system calibration for safe operation.
