Part of the fuel vapor recovery system. It prevents fuel vapors in the fuel tank escaping to the atmosphere.
Maybe stop going over that rock? I kid, I kid. Never heard of this happening to anyone else.
Is there any reason to think that they would not?
This explains everything. Thanks for sharing!
Yes I had the exact same thing happen except I never ran over anything and the dealership tried to claim I must've tried jacking my car up in the wrong place lol, I've been a race car fabricator for 40 plus years so the jacking bs is just that bs, they wanted 600 plus dollars to repair the issue and I told them to pound sand, $360.00 labor, $340.00 for the new canister, I bought a new canister online from parts geek for $180.00 and changed the canister in my driveway in 1/2 hour, the part I got from parts geek is a Motorcraft unit just like the dealer sells and in fact when I contacted Ford about the issue they didn't have anything to say even though I mentioned to them that putting the canister under the truck is stupid and it's vulnerable where it's at with no skid plate to protect it only a piece of cardboard with carpet on it and contrary to belief there are quite a few comments here on the forum by hundreds of owners who've had the same issue.
Is this something a handy but non-auto guy could do? Are there instructions anywhere?
Yes it is something the every day person can do, there's multiple what I call wire nuts, maybe 7 holding the cover on as well as 3 push plastic connectors, then there are 3 10mm nuts holding the canister in place and the typical Ford plastic fuel line retainer clips, it's quite simple if you just pay attention and take your time.
