GSS342 255 LPH EFI Fuel Pump

The Walbro GSS342 is a classic, reliable EFI fuel pump trusted by enthusiasts for years. This gerotor-style pump is designed for gasoline-based fuels and offers a high output capable of supporting vehicles making up to 550 BHP. With a flow rate of 255 LPH at 40 PSI, the GSS342 has been tested by Radium to flow 261 LPH at 43.5 PSI. It features a compact 39mm diameter and an 8.5mm (5/16") outlet. The pump draws minimal current, making it an efficient choice for upgrades. It is important to note that TI Automotive (Walbro's parent company) does not officially advertise compatibility with ethanol fuels, so users should research its suitability for alternative fuel applications before use. This product includes the fuel pump only and does NOT include an installation kit such as a filter sock, wiring pigtail, hose, or clamps, though it is compatible with the 14-0143 Fuel Pump Filter Sock.
