I starting My new project getting ready to install my new fuel tank by Ricks does anybody know the differance between the Walbro Gss340 pump and the 255 pump . and if the pumps are big enough? The Engine is going to be the new LS-7 with a cam or a warhawk 454 small block EFI non turbo waiting to see the results of the warhawk engine.
