I was thinking about that... I may have tried to top it off... I'm so used to trying to do that with my other cars....... I'm going to pull the back seat tomorrow, and see what I can find.... by design, iven if the charcoal canister is fouled you shouldn't smell any fuel. The whole reasoning behind charcoal canisters is to capture any fumes and reciruculate to the engine intake.... so the vapors get burned when the engine is running. I hope that when I get to the top of the fuel tank I can see a broken hose, or fitting..... something obvious..... I'm a tinkerer by nature and curious too boot...
