Gas vent next to gas cap. Is it supposed to have a cover?
07-02-2011, 05:15 AM
So my sister recently got a 2002 windstar and has had lots of trouble to say the least. Recently she was having trouble filling it up with gas. Getting strong gas odors etc..
She has a warranty from place she got it. So they took the car and said the venting sensors were the problem and fixed it.
SHe was showing me today that at gas cap/fillerneck there is a little vent hole to the left of the gas cap. She was told that she will just always have to have a gas smell coming from that, its the way it is.
Ive never seen something like that on a car myself. Is it a normal thing?
Im wondering if its supposed to have a cover or something that you remove when filling up.
I just dont see how a minivan can be designed this way to release gas odors. People buy minivans because they have kids to move around, it just makes no sense to me to make it so you smell gas.
Anyone have any insight on this?

Is the Check Engine Light On with EVAP codes?

On my '96, the little hole (~1/4" diameter) to the left of the fuel filler port is for a rubber grommet that holds the gas cap "rope".
Per emissions requirements, including those for gasoline vapors during fueling, I don't believe there would be a vent hole in that location by design. It seems that the EVAP system will not work properly if there is open vent from the tank, since it is sensitive enough to detect a loose gas cap. In many metro areas the fuel pumps include a vapor capturing system that surrounds the fuel port to keep gasoline vapors from escaping into the atmosphere.
