Left Fuel Tank - Sealing (5)

I convinced Rose to try her hand at the rivet gun today.  We finished up the handful of rivets remaining in the nose, and then I mixed up some more proseal and sealed all of the rivet heads as well as a few more areas along the rib flanges.  Fingers crossed that it'll be leak free!

The access plate got a few nutplates where the fuel level sender will attach.


The fuel level gauge comes as a float attached to a straight piece of wire that gets cut and then bent to match the depth of the fuel tank.  The wire then slips into a plastic slot in the sender that moves with changes in the fuel level.  Basically, the resistance changes as the float moves the arm.  Once it's installed, I will ensure it's accurately placed by measuring the ohms at the full and empty positions (the manufacturer lists what the correct readings should be).


Next I need to install the vent lines, but I had to order a flaring tool for that, and it won't be here until next week.  So I think in the meantime I will attach a few of the fittings that go through the access plate (for the vent line and fuel pickup line), then start working on the other tank.  It'll be interesting to see how much quicker the next tank goes together.
