Wire runs

[David47]

Thanks for the FAA info Phil. I think the reality, as Jim said earlier, that you get a bared wire close to sparking (earthing) and a fuel leak or more specifically, fuel vapour at the same time, the statistic on that is fairly remote. For certain structural failure probabilities, the FAA requires 1 in a million chance of it happening. I'm guessing the FAA requirement for electrical and fuel system proximity requirements is something similar. With proper tie wrapping and ensuring no potential for chafing, I would have thought all ok for running fuel and electrical systems within the same area. My particular routing was simply choice based on sensible routing for my build.
