For the LS1 I am thinking about using the stock electric fuel pump to feed my 255L high pressure pump. I will leave the stock lines up to the stock pump and to the feed on the new pump, then run 3/16 line from there to the fuel rails. The pressure regulator is mounted on the fuel rails and will dump into the stock return line.
Please, your thoughts on this approach. Am I asking for trouble with this?
