Removed the front seat, seat ramp and mid cabin covers.
Disconnected the fuel tank-to-fuel shutoff valve fuel lines. Cut 1 7/8 off of the outboard ends and reflared them. Reconnected them to the tanks and fuel valve. They had been installed incorrectly previously such that the LH tank was connected to the RH inlet and the fuel valve and the RH was connected to the LH inlet.
Installed fuel tank labels (fuel type and capacity).
