Gas Smell Empty Gas Smell

Post by KC77Monte Wed Jul 05, 2017 10:31 am

The last couple of times I have put gas in Monte and parked in the garage, the whole garage smells like gas for the next couple of days. Is this normal, I just noticed it the last couple of times I have put gas in it. Could it be venting from somewhere around the fuel tank? Thanks

Does your car have any steel braided rubber lines?

I am not sure if it does or not. Maybe a fuel line going bad?

That happened to me.
In my case it was a fuel leak in the steel line close to the catalytic converter. The leak could not be found until the crack in the line open and pour gas on the floor.

Be careful as gas vapor explodes. Turning the lights on in your garage can be enough to start a ball of fire if the room is not vented.

I suggest you to take care of it asap. One way to do is to go for a drive, then check every connection and use your nose to pinpoint the area.

I had that happen.  For me, the carb leaked into the manifold after the car was shut off, so every time you went to start it again later, you had to crank until it refilled the bowl.  In the meantime, the garage would reek of gas for the next 24-48 hours.

Mine only does it after I have filled it up. I got to looking last night and the odor is strong around where the filler tube meets the tank, plus it is damp around that area. I pumped about 5 gallons out and this morning I hardly noticed the smell. I'll check again tonight to see if it still smells. Looks like it might be new tank time.

You need to check the hoses that connect the fuel & vent lines to the tank unit.....the sender & fuel pick-up...above the tank.
I sure wouldn't park in a garage, until the leak has been fixed !! pale
