Today during three hours I made some more small works on the fule tanks. First I had to drill the nut on the fitting for the right tank fuel pick-up. This nut needs to be safety-wired so it has to be drilled first for the wire.



Then I drilled the rivet holes for the purge valves, the holes on the flanges are already countersunk.



Then I drilled the fuel cap holders, the holes on the skin get drilled and those on the fuel cap holder get countersunk. I choose to install the so-called "Deluxe" caps they look better and are lockable.



Then I installed the left fuel guage on the tank baffle. As the baffle is not as thick as the inspection hole cover supposed to hold the fuel sender, I used the cover to fabricate a reinforcing ring I'll mount inside the tank. The picture is taken on the inside of the baffle, I still havt or rivet the nutplates.



All the parts that will get Pro Seal during final assembly get sanded.



And to finis some plumbing work with the fabrication of the vent line and the fuel return line.
