i didn't replace anything on the fuel rail... i got this edelbrock kit on summit racing, its the walboro pump - wiring harness piece, and the occompaning fuel filter. i did my pump install right, i think i just have a leak somewhere beacuse my fuel tank isn't pressurized... when i prime 3-4 times it starts right up no problem, or when its warm out it fires up no problem.
obviously soemthings a miss when i dont get any hiss when I take off the gas cap.
