1995 850 T-5R - Fuel Smell

Post by wackenhut » Wed Mar 27, 2019 1:23 pm

I keep my car in the garage and was reading not to top off when fueling. What is the issue with the vehicle that when topped off causes the smell of gasoline to be so noticeable? If the vehicle is not filled all the way up, would this not occur?

I notice that the smell is also bad inside the car. The car has been sitting for a while and I just filled it up the other day.

Nothing is leaking from below. How do I get it to go away?

Thank you.

Gasoline expands with temperature. If you fill the tank to the lip with cold Gasoline, it will be overfull when the Gasoline warms up. This is why they say "insert nozzle all the way", doing so leave a little room for expansion.

Also check the Gas cap. On tight? Seal in good condition?
