The only way air can get in the fuel line is if you have a hole in it! Problem of course is were? I would run the fuel line from back to front and back again. Look for any wet spot that you can find. You may even have to drop the tank to ba able to look on top. I would suspect the problem is in the line before the high preasure pump, being as you are pulling air into the system. I have seen leaky lines allow air in, but not let fuel out.

1981 ford bronco failed emissions twice


Look behind the motor, next to the firewall. There's a vacuum check valve that keeps the air gulp pump from pressurizing the crankcase. Mine was shot; had the same symtoms. Also, make sure that the EGR valve is closing at low idle.

You don't need an engine light to check the codes. First, do a KOEO (key on, engine off), but, let me tell you, when this happened to me (1986 Full size with 302 EFI, multiport injection) NOTHING showed up. No one, not Ford, not emission specialists, nada, knew the vacuum check valve existed.

By the way; are you getting motor oil in the air filter housing?
