So I am in the final stages of parts collecting of doing the LS swap on my 1988 R30. I am planning on swapping to Walbro 255 (GCA758-2) pumps in each tank. The first post mentioned the switch can only handle 65 psi of fuel pressure.

I was only planning on running a single fuel pressure regulator (01-04 Corvette, Wix 33737) in the engine bay and reusing as much of the stock TBI fuel lines as possible. This will allow the fuel switch to dictate where/which tank unused/bypassed fuel to either tank that is selected.

Anyone see a problem with doing this way?

Thanks
