OK so my CEL came on on my New to me 2005 Expedition EB. "Unable to Bleed Up Fuel Tank Vacuum" is description, and i can validate that there is a vacuum issue, because i can only fill up my tank half way before it clicks off. i can restart the fuel flow and get another 2 gallons, before it clicks and, then it just keeps clicking off. so there is a restriction somewhere.
Here is what i have checked so far:
1. Removed the Fuel Vapor Canister and checked for airflow. Airflow is fine, no charcoal issues.
2. Removed the Vapor Solenoid and it is always open and when i apply 12V, it closes. that is how it is supposed to behave, and so it works as well.
3. i removed and check the vapor purge valve and checked it as well. when applying voltage it worked as well. (dont remember if it was open and then closed with 12v or other way around)
4. I have purchased a new Motorcraft Fuel Cap. Nothing changed.
I am also stuck as to where this one hose is supposed to connect. It was never connected to anything, and it is called a "Fuel Vapor Hose" and is item number 5 on the diagram below.
I just don't know where it can go. The hose it too short to reach the fuel tank, and really only reaches up to the fuel tank filler neck. there are NO ports on it for it to connect.
Can anyone check and see if they have a different fuel filler neck, and possibly locate where this hose connects too?
Thanks for the help.
