Tonight I finished making the last of the fuel lines, hopefully for the last time.
I put the stainless steel tunnel in place and it looks like it just barely touches the fuel valve:
I haven’t decided yet if I’m going to try to make a bump in the tunnel or try to secure the valve to the tunnel. The first option is the most appealing so far. While I was at the hangar, I also weighed our new fabric aft cabin bulkhead and our old aluminum bulkhead to see how much weight we saved. The fabric weighs 11 ounces, and the aluminum weighs 3 pounds 1 ounce. Yikes!
