I'm new to the board, and my name is eric from louisville, ky. I just recently purchased the zex kit for my 99 svt. I had the kit installed but I am being told that I need to have a vaccumm controlled fuel pressure regulator. What do I need to have this kit fully installed? somebody please help me out. I've been riding around with only the purge working for scare. What do I need to complete my kit? confused
