I am in the process of running my brake
fuel lines in my RV-7A. I have talked with a few RV owners and they mentioned how crowded the center tunnel becomes once you have wires, fuel and brake
lines running all together.
After thinking about installing the brake
lines per plans (which looks like a pain to snake around), I thought about an easier way. I made a test run and took some photos.
You can see that you don't have to pass the brake
lines through any bulkheads. In general the bending is simple and flaring is easy. The majority of the brake
lines are tucked under the lower longeron. I have a parking brake
but similar routing can be done with the standard firewall mounting bracket.
I don't see any downside to this approach but I would like some feedback from you all.
