Wire runs

[jrevens]

I used the same connectors for my wing lights as you did, Jim... at the wingtips & behind the seats. Ran my wires through 3/8” black thin-wall sprinkler system tubing through the spars. Running your fuel line towards the center takes 1 or 2 less bends than going around the right side like I did, which is good. I made an aluminum channel for a wire chase located under the pilots seat, and ran another bundle under the right seat supported by Adel clamps and the airframe tubing, transitioning to a couple more channels under the center counsel going up to the firewall area.

Thanks, guys,
It is always amazing to me how many wires we need for simple planes!

I've done the same routing as Phil; i.e. rear fuselage wire cables down the RH side and wing cables down the LH and RH sides. I've reserved the centre console area for fuel and brake lines only, rudder cables excepted of course .... Separates electrons from fluids.

Separating wiring from fuel lines-I've always wondered why this seems to be a big deal. What are the odds you will have a fuel leak at the same place and exact time that the wiring shorts out and causes a spark? Seems pretty remote to me. Only in a bad crash might these odds come together. I'm not saying its a bad idea, just personally would not go to too much effort to keep them separated.

In my centre console, the shut off valve is the only union. My fuel pumps are on the other side of the wall so if I had a leaky hose it would suck air not squirt fuel. I do try to keep them as separate as practical but if they are a few inches from each other I’m not worried

Jim, for me it has nothing to do with whether there's potential for fire or explosion if you run the electrons with fluids. After all, many larger aircraft have submerged electrically driven fuel pumps. It's simply a preference, and also helps to leave a bit more real estate in the console tunnel area.

That reasoning sounds fine with me. I just mentioned it because several others bring it up from time to time and I have always puzzled over it.
