Hi all,
I have had this issue for about 5 years now. When the sun shines on the gas tank or when the hot engine warms up the fuel tank I get a strong smell of gas. That happens with full or empty tank. It is a very strong smell. Good thing I'm not a smoker!
I have taken a look at the issue many times. Checked gas lines, no leak, Checked the vent tubes for kinks and it is operating fine, changed the check valve on vent tube and orientation is ok. After all this I pinpointed that the smell came from the gas cap itself (maybe a faulty relieve valve I thought) I changed it to an aftermarket non-locking (forgot the brand) and the problem continues. As pressure built up in the gas tank it seem that the gas fumes are vented thru the gas cap instead of the vent tube.
Has anyone had this issue with aftermarket gas caps? Should I spend the money putting a new OEM assembly? I'm out of ideas...
