Today and tomorrow will finish up most of the work for the RV-12's fuel tank. I am installing the new vent kit which is not required but seemed like a good idea since the fuel tank is disassembled for the Service Bulletin work. In looking over the plan revisions this vent is now part of the regular kit produced by Van's Aircraft.

Step 17: Reconnected the fuel return line to the fitting on the bottom of the fuel tank.
Reinstalled the fuel tank top after completing all internal work.
Turned tank upside down and put a dab of sealant on each new rivet.
I'm letting the fuel tank sit upside down overnight before completing the job of installing the sender unit plate.
