Fuel Tank End Ribs

We finished assembling the fuel tank end ribs as well as fuel level senders for both the wings in order to catch up before moving on to the left wing.

Root rib

Steel epoxy was applied on the outside of the rivnuts before pulling them for a solid bond as described in the instructions. Additionally, loctite was used for the threads before tightening the fuel line fittings. rib-1 Epoxy mixed before pulling the rivnuts. rib-2 Rivnuts pulled on the root rib. rib-3 Rivnuts pulled on the root rib. rib-4 Fuel line fittings installed.

Tip rib

Level senders

The original fuel level senders were disassembled, and sling aircraft provided angle brackets were used to mount the senders. Additionally, a pipe bender was used to bend the floats, and also tested inside the root rib for appropriate movement. In the end, a multi-meter was used to test resistance as the fuel sender float moves, works properly. level-1 Original fuel level senders disassembled. level-2 Original fuel level senders disassembled. level-3 Assembled fuel level senders. level-4 Assembled fuel level senders with floats.
