CJM Walbro GSS340 / GSS342 Install Kit
A DIY solution to securely install a Walbro GSS340/GSS342 fuel pump upgrade into your 2008+ Subaru Impreza WRX/STi and some Legacy GTs!
UPDATE: YES, IT ALSO FITS THE GSS342!!!
Included with the billet clamp that attaches securely to your fuel pump housing is a Viton bushing that replaces the stock o-ring for sealing the Walbro's smaller output barb to the housing.
Some minor trimming inside the pump housing is required to fit the larger Walbro pump. However, the modifications required are minor and the factory pump can be reinstalled if ever required.
