Product Description

The Walbro GSS242G3 is a universal, high-pressure, in-tank electric fuel pump engineered for high-performance builds. As part of the proven GSSG3 generation, it delivers 190 LPH - enough to sustain engines up to roughly 450 hp - without needing bulky external pumps. Its compact turbine-style design ensures smooth, pulse-free fuel delivery.

Built for simplicity and reliability, this pump features a slip-on 5/16" hose-barb outlet and filter sock inlet, making it suitable for many standard fuel hanger setups. It draws around 7.2 amps and maintains operation at approximately 50 psi (max ~137 psi). Manufactured in the USA with a lifetime warranty, it's a top choice for enthusiasts upgrading fuel systems on muscle cars, imports, or custom EFI installations. Note: Confirm fitment with your vehicle's hanger, wiring capacity, and fuel line interface. Not CARB compliant - may require alternate options for CA-registered vehicles.
