93 E-150 Gasoline Odor
Our 93 E150 has a strong gas odor under certain circumstances.Let me first list what isn't a problem:
- No odor when running engine with doghouse off (nothing leaking on/near engine)
- No visible leaking anywhere, no wetness on/around tank.
- Our repair shop found only a cracked vapor hose near one canister, which they repaired. Odor still a problem. I don't think they dropped the 35 gallon (midship) tank during this initial check.
- No smell in the gas fill door before or after running (which I'd expect if filler hose was leaking)
Odor is noticeable:
-- inside the vehicle only after it has been parked a while, but not while running
-- while running only if you open a window.
At this point I'm assuming I have a problem with a) a hole or a bad vapor seal on top of the tank or b) somewhere in the vapor system. Anyone with experience with this or recommendations? I'd rather rule out other options before having to drop the tank.
Thanks!

SAME problem in a '97 Crown Vic
I have the exact set of circumstances you have with my car so I'll be watching this thread for clues.
I know it's not the tank and no dripping/wetness.
My shop smoke tested the system, can't find it.

I had a similar problem with my '94. It was a ruptured gas vent line at the filler neck It's the small (overfill?) line that runs alongside the main filler hose/tube. It didn't leak noticeably at first but vented the gas tank under the vehicle causing a gas smell in the van mostly when you opened a window. I found and repaired the split line and the problem went away.
Ford sells the filler tube assembly as a complete unit and it is expensive as I recall. I bought some neoprene fuel line of the correct size and fixed it myself (without even removing the filler neck assembly).
Not sure if your problem is the same but it sounds very similar.

the fill hose (same age) was badly cracked. The fill hose was about $100 from
the dealer, but I just used a piece of Gates fuel hose for the vent.
The biggest problem was lowing our oversize tank. Not certain you'll have to do this with a stock tank, but if you do, you should probably play it safe and
attempt the hose changes when your tank is near empty.

Mystery solved (I think)
I took more time to investigate underneath the van, and I used a mirror to remotely view the top of the tank. There's a small leak on the fuel out line - looks like a loose connection, but of course the tank has to be dropped to get to it. I'm a bit surprised the repair shop didn't see it, but it might need to be drived for a few minutes for the gas to accumulate.

Replace them all
Don't take any chances, all the hoses are the same age, and have suffered
the same effects of aging. I could not believe how dried out and cracked my
filler hose was. Replace them all while you're under there.
It's worth the peace of mind.
