Fuel Smell during driving on 240 wagon 200 1986

Well, check the entire car over first and rule everything else out and then go back and take a whiff around the fuel door and if you smell gas then it is probably right there. Don't get me wrong, there are other places it can and will leak fuel but the filler neck is the most popular.
Take a look at the neck and see if it is getting tear drop shaped. People lean on those fillers while they are doing it and after years and years they start to deform and the only fix is a replacement.
The only other way I have used to diagnose these leaks is with a smog maching. I would set it on manual mode and take the sniffer and wave it around the filler and if I came up with HC (hydro carbons) then I knew it was leaking.

Good Luck,
Mark

Oh yeah, and remember if you are doing a filler neck on it to wait until it is darn near out of gas before you drop the tank.
