Gas tank issue/leak

So last time i filled my bko up I leaked gas and I though It was leaking from what I think has to do with the charcoal canister/vent system. Here are 2 views of the thing I am referring to.




Now should there be a clip or something that clips that piece down? Should there be a seal on it as well?

There is a seal in hole, in the tank. It just slips into the hole.

Sure its not the filler hose leaking?

Yeah it's that stinkin' fragile-ass tank vent thing! LOL :)

They ain't cheap from Ford. Be sure to get a new seal that -fits- -it-.

Yours might only be the seal leaking but you'll prob'ly break that flimsy
piece of crap taking the tank out anyway, BTDT -twice- and was being
careful as anything the second time too. LOL :)

What I did instead was went to using the single-type-vent that's made
from solid tough-assed nylon that Ford used in earlier models. YMMV

Sometimes you can find the solid nylon type layin' on the ground etc
at the wrecking yard. BTDT too. ;)

ps- Here's the Ford part numbers for the strong nylon type vent...
E7DZ-9B593-A (single port) valve
F6TZ-9B076-AA seal

Hmm, not trying to drop the tank. The body has a 3 inch body lift. And noticed gas was coming out in that area. I was gonna try to push it down. But I'm not sure if it clips in place or has something that secures it to the tank somehow.

I guess a body lift has got to have at least one benefit huh? ;)

No metal clip but it does sort{a} snap down into the rubber seal.
The seal might be cracked and causing the leak. ??

With your lift you can prob'ly pull the flimsy plastic vent out
where {the tank} sits and then pull the rubber seal and inspect it.

They go back together: seal back in tan{k} first then the vent.

If needs be, the old Permatex (shellac) is the best "gasoline
resistant" sealer BTW.

ps- I wasn't drinking honest. xD
Wife and kid distracting me, really, no kidding. :D

That's in the quote thread now. But I wouldn't do that... If the grommet is degraded enough to leak, it may crumble & fall into the tank if you try to push the vapor valve down. I'd either drop the tank, or cut an access hole to check it out. If you cut the access, you'll need to go slightly farther back than normal to get to that valve. Even with the body lift, there may not be enough room to lift the valve out.

I used a pry bar to pop it back in. I do remember the po saying that it got a new fuel pump, thinking who ever did the work never popped it in all the way.

Can you still see the rubber grommet all the way around the valve?

Yes I was able to see it all the way around.
I filled the tank and didn't have any fuel leak out anywhere. I'm satisfied about it now.
