I spent most of the evening making and remaking a couple more of the fuel lines that attach to the fuel pump:

1. The one from the outlet of the fuel filter to the inlet of the pump. I finally made one that I liked.
2. The one that goes from the pump to the firewall. It has two 180-degree bends, which made it easier to make and install than a straight one. It also provides some strain relief.

Next I'll tackle the difficult ones that attach to the fuel selector. I think I'm going to use a lot of coat hangers while making those.
