Fuel Systems and Brakes

Today I finished welding the elevator trim pushrods:

Before and After



I also took an inventory of the fuel system and brakes to figure up which fittings I’ll need and how much line to use. I went back to read the Beartracks and realized that Bob recommended 5052 Aluminum lines instead of the softer and much cheaper 3003. I asked him about this and he said that he certainly prefers the 5052 because of it’s superior resistance to fatigue cracking, but that the 3003 would work fine too. He said that the 5052 was still quite workable in it’s -0 condition. I also asked him about a primer, and he said that it really wouldn’t be necessary. He used to add them to his airplanes early on, but he says now days he doesn’t even bother, especially on airplanes with an electric starter. He said that the accellerator pump used during starting can substitute instead.
