The Walbro / TI Automotive GSS line is the Gold Standard for high-performance fuel pumps. GSS pumps are compatible with a wide range of vehicles including popular makes such as Acura and Honda. These in-tank, electric fuel pumps are compact enough to fit existing hanger assemblies without modification while the tried-and-true gerotor design is perfect for supercharged engines. GSS pumps are made in the USA and are known for their high quality, durability and performance.

Originally called the GSS342 this pump has been revamped and reintroduced as a G3. The GSS342G3 39mm in-tank pump features a 255 lph flow rate and is rated for 550 horsepower. The operating pressure is 40 psi (final fuel pressure will be set by the regulator.) The difference between the 340G3, 341G3 and 342G3 pumps is that they have different inlet orientations. GSS342G3 has a 0° outlet fitting to inlet orientation.
