I was able to pressure test the left tank today and after adjusting the fuel cap tightness I kept the balloon inflated for over 30 minutes. I'll give the tanks about a week to fully cure then put in 100LL in different orientations to check the seal. I also used soapy water on the left tank to check rivets and found zero leaks. Fingers crossed that the right tank will check out this well tomorrow. I then sealed the right tank baffle and completed all the steps for section 18 except for mounting.
Was able to start gathering parts for section 20 Bottom Wing Skins. I'll only be able to do a little bit before priming some of the parts and then wait to assemble the wing for additional drilling. I plan to continue with the flaps and airlerons until the next priming session.
