GSS342G3 255 LPH In-Tank Electric Fuel Pump

The Walbro GSS342G3 is an in-tank high-pressure electric fuel pump engineered to provide a robust flow rate of 255 liters per hour, designed to support engines producing over 500 horsepower. This high-pressure variant maintains significantly higher flow at elevated pressures compared to standard-pressure alternatives, with a straight-through inlet/outlet configuration that fits compact hanger assemblies without modification. Constructed with a proven gerotor internal design, this unit measures 39mm in diameter and 123.7mm in length. It is rated for a 20A fuse and features an 8mm outlet diameter. Because this is a high-output component, ensure your fuel system can handle the increased volume and pressure requirements. Installation requires standard in-tank fuel system procedures. Please note that Walbro fuel pumps are individually quality-assurance tested prior to shipping and do not carry a manufacturer's warranty. While this pump is a popular upgrade for a wide range of platforms—including 1990-2000 Acura Integra, 1992-2000 Honda Civic, 2002-2014 Subaru WRX, and various Toyota Supra Turbo models—it is a universal-fit component. Always verify your specific vehicle's hanger assembly requirements before purchase.
