Description

The Walbro GSS341 is a high-performance 255 LPH in-tank fuel pump engineered to be a direct replacement for specific applications, arriving with a compatible 400-857 install kit. This fuel pump is capable of supporting up to 500 horsepower and is specifically formulated for use with gasoline, though it is explicitly not for use with E85 fuel. The pump features a compact 39mm diameter body, an offset inlet with a strainer, and a 5/16" (8-9mm taper) outlet. Vehicle fitment is strictly limited to 1G DSM AWD models, including the 1990-1994 Eclipse GSX, 1990-1994 Talon TSi, 1990-1994 Laser RS, and the 1991-1993 Galant VR4. It is essential to confirm compatibility as this pump is for All Wheel Drive ONLY.
