I recently purchased a fuel system of 2 gt pumps , fuel line upgrade kit with rails and supposedly a modified fpdm from a friend that was all bought from lethal. I can't tell the diff between it an my stock one . Will post pics in few . Only diff is on cover the new one has a little red check on it. He ran this on his kb powered cobra along with twin turbo kit after. Looks like a stock on to me though .
