With help of Thomas, Dad & Jason, we wrestled the left wing into the fuselage and pinned into place with hardware 5/16" bolts that I ground into taper pins. Was surprised by how little space is left between wing skins and fuselage.
Turns out, the correct fuel line tube length needs to be 2.5 " from fuse skin. This is critical because the fuel and vent line come out directly across from the tank fittings.
