You sure have a lot of patience man. Not sure I could be that long with out the truck and they still have not figured it out.
Best of luck hope you get it back soon.

 

Here is the latest. They did find one of the cardboard disc from the top of a Motorcraft PM22A fuel treatment in the sending unit. It would restrict the fuel pick up tube off and on.

A word of warning. The sending unit and the tank had been inspected twice without finding the issue. The tech has to be looking to find it. Had the truck back five days and all seems good. I hope that is the issue.

 

I'm happy to hear you've gotten your truck back! Fingers crossed the issue is resolved. I can't believe they found anything in the sending unit after inspecting it twice and claiming to replace it once (see your post here). At any rate, thanks for the update and I hope this resolves the issue!

 

Can't believe it took all that. Restriction and aeration checks should always be performed with a failed pump.
Glad you have her back.

 

I guess this was not as unusual as I thought! As you mentioned, this had to be scrutinized carefully to find. Glad to hear this is resolved but keeping my fingers crossed for you as well.

 

Oh *****, I know I've dropped at least one of those in my tank.
