Walbro 255lph High Pressure Fuel Pump – Direct Fit for High-Performance Fuel Delivery

This Walbro is a 255lph high pressure in-tank electric fuel pump designed for consistent power in demanding conditions. This pump stands out by delivering up to 30% more volume at elevated pressures compared to standard 255lph models pushing over 210 liters per hour at 80 PSI while others drop to around 132 liters—making it the reliable pick for turbo setups, racing, and heavy-duty use where fuel starvation risks failure. Drivers choose it for its ability to support 500-650 horsepower on gasoline without compromising daily drivability, as excess fuel safely returns to the tank. Built in the USA by TI Automotive under the Walbro GSS line, it has earned a reputation for longevity and precision over two decades, ensuring your engine gets the steady supply it needs for peak operation.
