Well Great news! The leak test for the tanks held for 2-days. I'm declaring them leak free!!! What a frustrating process. Such little things make for a huge problem if not checked.
Now all I needed to do was to finish and secure the wiring on the tanks before I installed them on the wings. A couple of weeks ago I had my buddy Mike who is an AME stop by and show me how to crimp terminals for when I installed the ground wire. He was able to show me how I should install the lock washer/ring terminal on the fuel sender.
Now that I was ready to complete the wiring for the positive terminal, I was able to confirm that I have the assembly/installation correct. Once I had the positive wire installed. I then taped the wiring to the back baffle in intervals. I had discussed how to secure the wiring with Mike so that it doesn't rub/chafe once installed on the wing. He had suggested using a small dab of proseal. Taping the wiring down keeps it exactly where I wanted it to be. I used a service loop on the wiring around the sender to help ensure that wiring is not pulled off the terminals in the event the wiring is pulled too much in the future.
I mixed up some proseal and dabbed some on the wiring.
