Re: fuel odor

If you topped off the tank fuel might have gotten in there, either way the cannister is the most likely suspect. I've never had that problem, but there are periodic posts about it. I suppose you could always check the purge solenoid/valve and see if that checks out and make sure no lines are off the sender or cannister, etc...

Re: fuel odor

If the tank was low, an overheating fuel pump may be increasing the vapor load beyond the capabilities of the charcoal canister. The canister should be removing the gasoline vapor, so it can be pulled into the intake manifold and burned in the engine. You shouldn't smell anything at the rear of the car.

When I had a problem with fuel smell at the rear of the car, it was a cracked rubber line from the tank to the canister, but the canister itself did not smell.
