My bloody Capri axle is taking up too much room on the offside of the tunnel, the upshot of this is that all the services will have to go up the
nearside of the tunnel.
There is a lot of talk of not mixing fuel and electrics on the same side of the tunnel, is this SVA or just legend?
I asked my local SVA man this question a while back, as i had all three 'items' Fuel, brakes and lecy', clipped, and tiewrapped
together down the tunnel because of avaliable room, he had his doubts, but couldn't find anything in his book that said you couldn't and so
said it would be ok, Hope it helps

IIRC the SVA manual states that you cannot support the electrical and fuel lines together ie using 1 P-Clip. Common sense that one but maybe someone
has done it.
Our brake and electrics go one side, fuel other all p-clipped seperately.
Put the brake lines and electrics at the top and the fuel line at the bottom, or vice versa. If your wiring is secure it shouldn't be a problem. Brake fluid is flammable so why should it be safe near electrics.
Brake fluid has a pretty high flash point and dosen't form an inflamable or potentially explosive vapour at ambient temperatures the way petrol
does. I the old days in long distance racing quite a few brake fluid fires did occur but always because somebody spilled brake fluid on at hot
exhaust the resultant vapor was then ignited by a spark.
As for brake piping and wiring there is no reason not to run them inside the car as long as they are protected some builders create a false tunnel
top an inch or so deep along the top of the chassis backbone.
I had some drips of brake fluid on my garage floor ignite with grinder sparks.....
its reasonably flammable!!!!

I found out years ago when Alf the welder bloke was under a car and set fire to the underseal. He reached for his trusty extinguisher (Squezy bottle)
and got the one the mechanic had filled with brake fluid for topping up. It went like a flashover and took his hair and eyebrows off. We didn't
laugh of course as it was a serious matter .
I wasnt there on the day, and didnt see it, but there was a funny event when a fire extinguisher guy came to our company to test our extingushers.
He was pressure testing a foam filled cylinder in the back of his van when it exploded. Guy emerged from his van in a mass of foamy stuff totally
shell shocked. Apparently the explosions are rare, and can kill.....

I'm going to put them all down the same side. They are neat as hell and all properly clipped, the loom is in a corrugated liner and has no connections inside the tunnel. I have mounted them all on a pre drilled stainless strip, which is 3" wide and riveted to the tunnel side.
All my services run down one side of the tunnel, had the SVA last week (failed)
. The SVA man said they were fine all together, as long as the
electrics are basically insulated. my loom is taped and then spiwrapped through the tunnel and everything is held in place with plastic P clips. Oh
yes and i ran a strip of ali 3 inches wide down the tunnel to mount the services on, clipped every 250 mm.
There was a demo on top gear a few years ago that was very illuminating:- they used a pipette to squirt petrol at the exhaust of a running car, it
hissed and dripped thruough to the floor. Similar pipette now with brake fluid, instant 2foot flames.
Apparently this was the cause of the majority of fires in accidents, push on brake reservoir dumping its load over the exhaust.
