Re: Fuel sample valve - need help
Is this the type of fuel system that doesn't have a fuel return up in the engine compartment ? I think the factory had the return and possibly the regulator back by the fuel tank . You may want to re-engineer that so it is similar to the old LT1 , which regulated fuel pressure on the return side of the fuel rail . Once you do that , the fuel sample valve will be easy to plumb in . That will then be similar to how I plumbed up my Oldsmobile Quad 4 .
