Gas venting from upper left

Is it normal for gas to vent out at the first gap from the top left side of the tank? I filler it up today about 2" from the top and as I snapped the cap down I could see a small vapor then slow drip down the left side......any thoughts or normal.

That's the gap whee the air box and the tank meet. I can't imagine a situation where there'd be fuel seeping from there. There is no opening, connectors, seams or anything in that gap where any liquid could get out. Unless that is the tank were damaged, but I think you'd know as it'd leak a lot more and it's unlikely it'd sit flush if it were.

Is it possible there was just some water residing in the gap from a very recent wash? Pushing the cap shut might have just put enough pressure on the tank to squeeze it out the gap. Was it definitely fuel? Did you sniff it?

I would take the tank off. Drain it and inspect the inside for leaks.

tank is leaking and it sounds like your tank vent might be plugged

Thank you all for the help. I did blow air up the vent hose and could hear it out the cap.....light air that is.

The tank looks like a small hair line weld as it appears to be more straight than an impact
