My 1995 Tracker smells like gas all the time. Inside and outside. While driving and just walking by it. There are no leaks in the tank. The tank is dry all around it. I have gone over all the connections and hoses. I thought it was the vent hose being loose or fallen off, but I checked that too. The only thing I can think of is replacing the vent hose, in case there is a hole in it, but I followed it all the way from the tank to the filler and don't feel anything wrong.
Have you checked the evap system? If the canister is damaged in any way, it can cause fuel vapors - also if the solenoid to it is not working properly, the canister can fill up with gas. Because of this system, it is recommended never to 'top off' when you fill up with gas.
I checked the charcoal canister. I have a manual that told how to check it by blowing air in one of the tubes. Air should go one way but not the other. Can't remember axactly what the instuctions were, but the canister did what the manual said it should.
I'd be lying if I said I never top it off, because I do. When I say top off, I mean when the pump stops, I just go to the whole dollar.
I would say the vapors are worse when the tank is full, but not by much. I can still smell it all the time.
The evap canister works off of a vacuum solenoid. The ECU turns this on when your car has warmed up. With the key on (and car not cranked previously) you can first disconnect the vacuum hose from the solenoid and apply 10 hg vacuum to it, to see if the solenoid holds the vacuum. It must do so for the canister to work properly.
That was the very first thing I checked, and made sure it was sealing. Probably should have mentioned this isn't a new problem. Been going on for a while, and the check engine light went on around the same time. My local parts shop doesn't have the right connection to check for codes. I guess the 95 is different than later years.
You don't need any 'connection' to check for codes, other than a metal paperclip. Here is how: Check Engine Light
One of the first things that used to be asked on the forum was whether or not the CEL was on or not. It is surprising how many people neglect the fact that this light is on, drive with it on forever, and never check codes. There is always the possibility, that your ECU is trying to tell you something! Post whatever code you get.
