Description

The Walbro GSS342 is a high-performance in-tank fuel pump engineered to meet the demands of modified vehicles. As a leading name in fuel pump technology, Walbro delivers reliability and power, with this model capable of supporting up to 600 crank horsepower. This makes it an ideal upgrade when increasing boost pressure or installing larger injectors to achieve greater engine output. Each Walbro GSS342 kit comes complete with the 255 LPH (Liter Per Hour) fuel pump and a universal installation kit, facilitating integration into various vehicle systems. Manufactured in the USA from durable metal, this fuel pump is built for longevity and consistent performance. Please note that Walbro does not offer a warranty on any of its fuel pump products. Installation may require modifications, as the Walbro unit features larger electrical connectors than factory fittings. This means the stock connectors will not fit, and you will need to cut off the factory connectors to adapt the wiring.
