2003 XLT 5.4 FUEL LEAK WHEN FILLING UP ONLY

[SEPTIC PROFESSOR]

When I fill up all the way, there's a profuse gas leak which occurs but ends in a minute or so.
Has anyone had first hand experience fixing this yourself and if so were there any parts that
needed replacement ?
Thanks in advance.

Maybe you should look at some different forums.

An excellent suggestion, found exactly what I needed on the F-150 forum.

He's on the right forum, just turned out nobody had similar issues!

Two trolls for the price of one !

Sounds like the filler neck has deteriorated.

Mine does this, but only if I top it off more than a few cents after the pump shuts off.

 

[SEPTIC PROFESSOR]

Thanks Paul, I've learned to stop filling as soon as the pump nozzle shuts off.

Look under truck under the panel, its probably just the filler leaking and not the tank or fuel system.

You may be pumping gas, into charcoal canister/evap system. One or two clicks only.

Either I'm lucky with my 2000, I top mine up at least $1.00 or more after the pump clicks off. I've never had a leak, or any smell. Most vehicles though you can't push it like I do. When I ran a motorcycle service dept a few years back, we used to repeatedly tell customers to leave at least 2 inches from top of tank. I'm with Brian, you've got a hose issue that should be diagnosed, and repaired, fuel leaks aren't something you don't want to ignore. Fumes in the cab, as well as possibility of fuel splashing on exaust, or any hot part, is not a good thing.
