Firewall pass throughs: 4 hours


  • Drilled holes for wiring and throttle cable pass through's using 1" bi-metal hole saw backed up with a piece of 2x4. 
  • Drilled and installed wiring pass through fittings. These stainless steel fittings were installed with a layer of fireproof sealant. They will later get wrapped in fire sleeve with the wires in the middle of another fire sleeve and more sealant.
  • Installed throttle cable spherical fitting. This fitting was relocated slightly to clear the fuel line.
