If you are using the fuel caps with the sight tubes from glass, then the caps that close the top of these tubes are most likely cracked. It is not easy to find a cap substitute, but closing the top will solve your problem. The low pressure over the tubes creates these bubbles.

This is the first time ever this has happened. Also, the last 2 flights, I have a tiny amount of fuel leaking out of the vented cap on the header tank. I flew the pattern 3 times tonight, and the fuel did the same thing all 3 times. I did have full fuel, but still, I have never seen this before. Any ideas?
