1. The balloon on left wing tank was still inflated after 24 hours. It was only slightly smaller and most likely due to the drop in temperature during the night. The controll was also slightly smaller. I'm calling thi s tank sealed and fuel worthy!
2. Set up the right tank in similar fashion to the other. The first try revealed a leak coming from the ballon attach point. Tried another balloon and sealed it better. No leaks to report after 7 hours. Will not be able to check on it until tomorrow afternoon.
