How are people routing the wiring for their fuel pump and potentially their floscan in the tunnel?  Are you routing the wires back and under the seats or forward and up the fuselage?  Just curious what ways people have done this... pictures are always nice.

Forward and up the firewall

Ben,



I think you can go either direction if you want. I ran mine back

and under the seats and forward...that's kind of the long way

around but it did let me keep the tunnel cover pretty

sealed up.  You'll notice that the cover has a hole where it

allows your brake lines through.  If you run wires up, you'll

want to enlarge and protect the edges of that hole.  That

#1 flying RV-10 had wires run up there in a bundle with no

protection between the wires and the tunnel cover, and they

were pushed out and rubbing on the tunnel cover's metal

edge.  As long as you take care to protect the wires

and give clearance, you can go that route.



I went the other way just to stay away from that tunnel

cover gap, the lower firewall heat by the exhaust, and

because it was an easy wire run to get under the seats

where I also had control stick wires to route to the

panel anyway.



To each his own on this one.

Tim and Deems have both offered excellent pointers.  Dan Checkoway did quite a bit (his RV7 website) on failures of his wire support brackets (Clickbond, DP100, 10 minute epoxy, electric tie wraps and two way tape) along with chafing damage on both wire and sheet aluminum.  All of that in his RV7's first year of operation.  

   

The SFAR88 mods that are such a nemesis at work, are a result of 20th century (WWII) wiring techniques which needed updating on 21st Century aircraft.  Standoffs, distance between supports, routing, proper size of wire, bundling techniques, heat buildup and a plethora of data lead me to say "Ask Stein".  A little wire here, a little more wire there and it adds to grams, to ounces, to pounds, and finally to reduced "Useable" weight.  You can always pencil whip your GW limitation to keep the VANS approved Useable number (as was recommended by a Hired Gun),  "I sure don't encourage that without Static Loading of the Wings and Landing Gear to the new penciled number".  

   

The standard is yours to establish.

I see no reason to route the wires aft ..... they'll end up terminating 

behind the instrument panel anyway.  Unless I'm missing something.  What 

prompted the question???

Curiosity more than anything.  I was thinking that if somebody was dead set

on one way or another they would have a reason and probably say it.  I

couldn't quite decide.  



After looking at it I've decided to head aft with the wires.  I'm also

starting the stick wiring and safety trim this weekend which are going to be

under the seats as well so I'll be able to follow the wiring runs from this.

I'd rather not have to add additional Adel clamps and such up front and

worry about routing up through the tunnel cover.  The less I have to crawl

under the dash for in the future is a plus in my opinion.



Thanks for everyone's inputs.



-Ben



Who knows I'll probably change my mind 3 times before I actually proceed.

You know how that goes
