So I bought a 40 Ford pick up today. It has a 350 TPI. Went to the gas station, filled it up. Driving back home and it started making loud whirling noise, thought maybe fans but kind of too loud. Anyway pull in driveway and turned it off, all noises stopped, went to restart and would only crank, what the hell?
After thinking about it more, I didn't get the gas cap screwed on right. So I stuff the filler neck with a rag and it starts again, parked it in garage.
My question is will air coming in thru cap, since I never got it screwed on properly cause the fuel system to suck air? My thought is since it's a high pressure return type it must be sealed?? The loud noise must have been the fuel pump pumping air?? Please TPI experts confirm or deny, Thanks.
