I noticed gas coming from an inspection panel underneath the right wing. We pulled the panel revealing the fuel selector. No fuel was leaking from the selector itself.

After troubleshooting a bit, we also noticed that the fuel vent for the Aux. Tank was completely clogged. We tried everything we could to clear it up to no avail.

My question is: Where could gas possibly come from in that area besides the Aux. tank, selector, and appropriate hosing? We can produce a leak on the ground, but can't find the origin.

Does anyone else have any experience with a situation like this?
