Gas smell on 2018 Defender H8
Out for a ride today, when backing up, we smelled some gas. This is the second time this has happened. Today it's a bit warm, the defender was sitting in the cool garage before the ride and the outside quite a bit warmer. I turned the gas cap only to find it was a bit damp with gas on the lower edge. When I loosened the cap it did hiss indicating the tank was pressurized. I think they are like cars where they run with pressure in the tank. I find no evidence of an actual gas tank or fuel line leak. And we ride nearly 100% on gravel or pavement and have been on rough trail nearly never. So the chances of some rock damage is very low.
My suspicion is that the gas cap did not seal well. The other evidence of this is a high pitched squeal, just before the gas smell. I think this was gas vapor coming past the cap seal making a whistle sound. I also notice that when tightening the cap it clicks after very little tightening force.
Has anyone experienced this? Any suggestions on something else to look at? I plan to call the local Can Am dealer tomorrow and ask them what they thing.
Thanks in advice.
