OK, to clear confusion. There is a spot on the tanks top where they hold water and rust through. Wouldn't be seen in the trunk. You said its a recent replacement tank so this probably isn't where your issue is.
Ok,... I'm an idiot!! For some reason when looking at the picture Dave posted, I was picturing the spare tire well in the trunk!:rolleyes: I see what you're saying now.
I WAS told that the previous owner replaced the trunk. That being said,... even if he didn't. If that was my issue, I would think I would have an issue all the time since that spot is pretty low on the tank. The only time I have an issue is immediately after filling the tank, and especially when braking and turning, which is what led me to think about the venting.
