I have read the how to but not sure if that is for all models of coupe.... does anybody known if the Walbro GSS340 as in the group buy is a direct replacement and how easy it is to fit? I don't particularly want to break anything whilst trying to install it especially if there are brittle fiddly bits.
I think the GSS342 requires some modifications and not sure if the GSS340 needs the same work to fit, whats the difference between the 2 pumps?
