Gas smell

[BFGTAKO]

Hello,
I have a 2002 Cruiser and every time it gets hot outside or I change altitude quickly I get a gas smell in the cabin. When i remove the gas cap tons of air comes out and it also spews out gasoline. I haven’t noticed it for a while but it was 97 out yesterday and the smell came back. The dealer, naturally being incompetent has no idea what the problem is and of course it never happens when I am near the dealership so I can not show them. It was really bad last summer when I was off roading in Death Valley, it was 122 out, and I actually had to turn around because I was so worried about it. Any thoughts on what the problem might be? Thanks for the help guys.

Mike

It sounds like your fuel tank is not venting or not ventilating properly. I believe the fuel tank is vented back to the charcoal cannister that is apart of the EVAP system along with a Vapor Pressure Sensor (VSV). Don't know...only guessing...maybe something apart of this system is not functioning properly? I don't know if the fuel tank cap has any hi-pressure venting of its own or not?

Yea Toyota said that the cap has an over pressure vent in it. I thought that that would solve the problem so I bought another one yesterday; however, the problem reoccurred after that.

Hi,
Replacing my charcoal canister totally cured it. I wish I had done it sooner!
( I waited for two years before I took people's advice. )
The smell was more noticeable when I drove around corners and also very noticeable as the tank emptied.
Hope this helps!
