I have a 02 ss with two pumps one in tank and one out tank. Intank is walbro and out tank is a vortech 50/70 pump... I want to put a performance fuel pressure regulator but do i bypass the original one in the tank or wut do i do? And im at approx 55psi (key on eng off) with in tank pump on and out pump off... Now when both are on the pressure drops goes to 55 and slowly drops to bout 40 like injectors are leaking or something... But only w/ both on!?! Any ideas?
