I tackled the engine primer installation today. First I fabricated a firewall doubler plate and primer solenoid mount bracket and riveted them to the firewall. Then I screwed and lock wired the primer solenoid to the bracket. Next I ran the primer line to the #1 and #4 cylinders. Then I fabricated clamp brackets and clamped the primer line to the engine monut. To finish the work session for the day I replaced the MS21219DG4 clamps I had used on the park brake and cabin heat control cables with MS21219DG2 clamps as I had received a parts order with the correct size.
