Brief Description: Fitting fuel tank in right wing 2 of 4
Extend the lines square from the spar for both the vent and quick drain.
Attach two layers 1" x .125" thick self adhesive cork along the rivet lines of the spar rivet on the tank back.
Measure to the center of both the vent and quick drain from the cork surface on the back of the tank.
Transfer the dimensions to the leading edge skin. The quick drain side is offset, (note line ahead of spar web) because the upper and lower spar doublers don't extend the full length of the 15 gal. fuel tank.
Drill out clearance holes in leading edge skin for the quick drain and vent tube.
Mark top of spar for the locations of the hat stiffeners and spar doubler end so their locations can be transfered to the tank.
