A good Christmas present! I had a poor sleep last night disappointed that I had a fuel tank leak, after all my careful sealing of the joints. In reconsidering my test, I thought it would sure be better if I tested the filler neck and fuel cap as well, so installed them. Just in case my leak had been there, I pressurized it again - and no leaks! Well, none in a 15 minute check at least. I will leave it a couple of days to make sure it has no real slow leaks, but I feel confident that I have a tank made with no leaks now. The mailman brought me my aircraft registration so I can prove that I own Air Force 1, proud of that little piece of paper.
