Question about 1990 Ford F350
When my truck sits for a period of time it seems that the fuel is draining back to the tank. i have to crank on it for a while (25-50 seconds) before it will start. what is the likely culprit? i cant find any leaks (hoses, connectors, injectors, or the pump) everything is dry.
Sounds like the check valve in the fuel pump is not closing causing fuel to drain back.

If fuel injected you might check the fuel filter and pump pressure.
If carberueted you might check to see if the float and needle valve are sealing properly.
