can this pump be plugged into a thrid gen fuel tank and will it hook up to the 97-98 corvette fuel rails if I decide to use them instead of the stock Ls1 fuel rails. it mentions on the website that the gm return system can be kept, is it talking about the Ls1 fuel rails or only those fuel rail that have the hookup? the wiring is supposed to work with the lsi wiring harness too right?
