I finished up the fuel tank today by installing the fuel pickup tube and access panel. Once I had the fuel pickup tube positioned corrected, I tightened up the fitting and gooped proseal over it to keep things in place. I also added some more proseal over the inside of the BNC connector as well as the over the interior fittings for the fuel vent line. Once all of the interior work was done, I installed the cork gasket and screwed on the access panel. The final step was to proseal around the edges. This should allow for a good seal as well as for easy removal down the road.
