I have a 98 5.7 I replaced the check valve, the fuel pump and both filters. I only have 12v at the pump while cranking then no voltage when key in run mode. Is this normal, does it run on Ventuari after it starts? I have been running street gas with ethanol (regular grade) for years. I've been told ri stat buying marine gas because it's hi test and no ethanol. I have a rebuilt carburetor ready to go on now but id like to find out if I'm supposed to have 12v constantly when running. I've checked the pick up tube in tank also.
