I was not able to take pictures of the fuel assembly since my hands were fill with Flamemaster tank sealant. Was a really messy process, and after trying few ways of applying this stuff, the best resuls were with a popsicle wood stick.
I'm glad I check that all rivets fit before starting putting this stuff, it gets really messy. I will now let the sealant set for few weeks, and will start working on the right wing while the sealant cure. I will then check for leaks.
