I seem to be losing the prime from my fuel line. After setting for a day or two it doesn't
want to start until I leave the ignition on for 20 to 40 seconds. I can hear the pump clicking
and as soon as it stops it will start. What would cause this problem. Thank You
Maybe you can make some sense of this. Don't know if it will help, but is 1989 F150. Click for full screen
OR this...I scaled it up
After setting for a day or two it the fuel leaks back to the tank ( no gas on the ground ) and loses it's prime and needs to pump and fill the fuel lines back up before it will start.
