After successful pressure testing, the tanks were filled with unleaded fuel and allowed to set from 12/31/07 to 1/19/08. Again, Rans recommended at least two weeks to allow the tank material to interact with the gasoline which they claimed could result in an inch of tank elongation, obviously important to do before riveting the tank to the wing structure. A tank support tube was added to the wing frame and the tank was set in place with mounting brackets attached. Once the tank was clamped so that it lied uniformly along the compression tube and tank support tubes, the mounting brackets were drilled and riveted into the tubes. Below are the installation pics from one of the installed tanks.
Once I get the wing ribs riveted to the spars, I'll then install the fuel lines.
