More wing fit related work: 3 hours

  • Fitted the right wing fuel tank attach bracket
  • Drilled the bracket on the fuel tank for an AN4 bolt
  • The majority of the time was spent working out the connecting fuel line for the left wing tank to the fuselage. The left wing tank has a more complicated fuel line connection because it is the aerobatic tank and the fuel port is in the leading edge of the tank.
  • I made a rough, hand bent piece of tubing as a trial run then used the tubing bender to make the final. The fit has to be exact so it took a while to get it dialed in.
  • I had not made any fuel lines in a while so I practiced flaring the tube ends on some scrap.
  • I carefully polished the ends of the fuel tubing then made my flares. Everything turned out great and fit well.

Checking the fit for the finished fuel line for the left tank:
