Completed the final fuel line connections - but left off the last line to the carbi. Poured 10 ltrs into each tank and rocked the plane to swill the fuel around the tanks - then used the electric fuel pump to pump 2 ltrs from each tank into a container to flush the lines. Used a fuel cup to open each fuel drain to test the seals. No leaks so far. Then connected the final fuel line to the carbi and safety wired the fire sleeve in place. I have a small leak from the dynon fuel flow meter connectors. Will remove the connectors and use a different sealant (I used Swalk paste on advice but it seems to be not sealing ...)
Bought a new proper battery charger (C-Tek) to leave permanently attached to keep the battery in good condition. Fitted the permanent leads with the plug connector for the charger.
