After a few days break from the tanks, I returned today and finished riveting the right tank ribs.

After taping of the sealant fillet line, mixing the sealant and applying it to the inboard end rib, I cleco’ed it to the tank.

All the rivets could be set with the pneumatic squeezer; nice and easy!

..a look inside after riveting! (tank is upside down)  The vent line fitting and fuel level sender connector has not yet been installed.

…but now they are!

Next I finished the fuel level sender wiring.

Finally I riveted on the outboard end rib. That’s it! Done riveting tank ribs – I hope!! 😉
