I've been suspecting a small leak on the right main tank. When the tank is full, we smell gas in the cabin. Sure enough, I pulled the main tank yesterday and found this obvious leak near where the bolt that holds the vent is located. I tested the vent tube, and unfortunately it's not the vent tube. This is a bit of a mystery because there is no fuel leaking from the lower bolts holding the vent. I would assume if there is fuel between the walls in the tank, it would leak out of the other mount points as well. Has anyone seen this problem? (Working with my A&P)
