I have done the leak testing on one of my fuel tanks and I am satisfied that no rivets, seams, or fittings leak. However, my balloon doesn't stay inflated all day. It held well for a couple hours last night but in the morning it was in sad shape. I re-inflated the balloon and went to work, then came home tonight to a deflated balloon again.
Soapy water sprayed on the tank shows only one spot where any bubbles form. The edge of the fuel cap. It is a very slow leak.
I feel pretty confident that the tank is fine. But I wanted to check here for some reassurance. How long should that balloon stay inflated when I test the tanks? Is a very slow air leak through the fuel cap any cause for concern?
