Fuel smell after filling

[loricechris01]

HI, I have been having an issue with my Yaris/Belta 2009 VVT-i model. I get an extremely strong fuel smell outside the car and inside the car cabin only after fulling the tank (No drips or mess during fulling). And the smell is extremely strong while driving to the point where the fuel smell burns my eyes. There are no signs of drips on the fuel tank itself, the fuel return line was changed and the fuel pump was temporarily sealed off to see if it'll help the smell. After the car loses a bit of fuel from usage the smell goes away.
Help! Does anyone have any advice?

Don't try to add more gas after the pump clicks off.

Take The car to a mechanic and have it looked at NOW!

I've had multiple mechanics check it for me and there wasn't a solution yet. Right now I'm just waiting for the fuel level to drop so that I don't get the smell :frown:

In that case I agree with the poster who said when filling the car with gas, don’t add any after the first click of the pump

I would have to do that from now on. But what do you think can cause an 'overfilling' issue for it to smell that bad?

There are hoses near the fill port they go to a charcoal filter which stores gas fumes. Probably some of the extra gas you were pumping in after the first click is going down that hose to the charcoal filter.

That can ruin the charcoal filter and the solenoid which turn things on and off in the system

It’s very unwise to pump gas after the first click :cool:

well you said it had recent work done i would suspect that right away, fuel leaks are not something to brush off, get that shit sorted fast as its a rolling fire hazard as it is now

if your filling anything made after the mid 90s beyond the first click(unless it clicks off VERY early) your fueling things that shouldnt have fuel in them

old stuff pre 80s often needs to be seriously topped up as the pumps are too sensitive for them and can stop crazy early

if i was to place a guess your simply overfilling it and need to stop doing so, secondly the suspect would be the evap system or the tank to fuel seal

both options are viable and its pretty easy to know which based on how long it takes for the smell to go away....does it come back on a hard right hand turn?..if so its the tank seal

Overfilling will flood your fuel recovery system which is big buck$$.
