Fuel Pump - 255lph

The Walbro GSS343G3-3 fuel pump is a high-output electric in-tank pump designed for performance fuel systems and engine builds that require reliable fuel delivery at elevated flow rates. With a flow capacity of 255 liters per hour, it serves as a direct replacement for OEM and custom fuel systems that demand serious pump output.

This pump features an integrated filter sock inlet that protects internal components from tank sediment and contamination, thereby extending service life across varied fuel qualities. The 5/16-inch hose barb outlet accommodates standard fuel line sizing and connects directly to aftermarket fuel rails, regulators, and distribution blocks, ensuring compatibility with a wide range of setups.

Ideal for builders and tuners, the GSS343G3 is perfect for street performance cars, racing applications, and engine swaps where OEM pump capacity is insufficient. Buyers upgrading to larger injectors, adding forced induction, or running custom ECU tunes can rely on this high-volume pump to maintain fuel pressure stability and prevent lean-out conditions in modified engines.
