Fuel system covers and mounts: 7 hours


  • Riveted fuel pump cover together
  • Edge finshed and deburred fuel pump mount plate (complicated - a lot of curve and protruding edges)
  • Modified fuel valve cover per plans for electric boost pump
  • Edge finished and deburred valve cover
  • Made 15/16" spacers for drilling pump mount and forward cover to floor angles
  • Tweaked spacers to get thicker pump mount and thinner forward cover to line up
  • Fine tuned fit of pump cover, valve cover, etc.
  • Drilled fuel pump mount to floor angles with angle drill
  • Drilled fuel pump cover to valve cover for plate nuts
  • Deburred everything
  • Did initial trimming of forward cover to fit flush with fuel pump mount
  • Also figured out the location for the handheld fire extinguisher mount (going to mount on left spar cover)
