TI Automotive Walbro GSS342 255LPH In-Tank Fuel Pump Kit - Universal
The Walbro GSS342 is TI Automotive's 255 lph high-pressure in-tank fuel pump. The GSS line has been a go-to upgrade for petrol EFI engines for more than two decades, replacing tired or undersized factory pumps on modified turbocharged and naturally aspirated builds.
This listing covers the GSS342-400-959 kit. The GSS342 suits a wide range of in-tank applications – confirm your pump hanger, inlet style and outlet orientation before ordering. Looking for the Evo-specific kit? See the Walbro GSS342 kit for Mitsubishi Lancer Evolution.
Note: This pump is rated for petrol – for E85 or flex fuel, choose an E85-rated Walbro pump. Ageing factory wiring can limit the voltage (and flow) the pump receives, so a dedicated relay/hard-wire kit is recommended on older or high-output cars. Installation by a professional is recommended.
