I installed the fuel tank in the left wing. I connected the fuel line to the rear pickup fitting prior to install. Riveted root rib including the AN3-5A bolt on the top hole of the rear flange. I installed the fuel sight gauge with hose clamps provided. Finally, I applied proseal around cap assembly to form fillet as written in the plans. Left wing construction is complete except for wing tip install. I've decided to wait for Aerosport to offer their new carbon fiber wingtip to make final decision on which tip to install.
