Securing Cabling in the Propshaft Tunnell
Hi Folks
Not a lot of room on the box section to fit P clips for both fuel line b pipe and cabling. I have seen examples where the fuel pipe (copper) is P
clipped and the wiring is cable tied to the pipe, close to the clips. Looks like a sensible idea. Is that OK for the SVA man?
Also - is the SVA man OK with cable ties in general for fuel line and brake pipes?

NO - on both counts.
Zip ties securing cables surrounded in conduit yeah, but they need to have their own mounts securing the cable ties to the chassis.
P clip the brake lines to the chassis too please, not cable ties. Chaffing could wear down the pipe & eventually - no brakes.

Just imagine when the pipe wears through the electrics, or the other way round...  That's the way that the SVA man will look at it (just
before he rejects it).
Fuel line and brake pipes should be held with P-clips, or the special clips available for brake lines if you prefer.

don't cable tie anything to fuel or brake pipes, Mr SVA will send you home. Best to use P clips spaced at 20cm or less to support the brake,
fuel and wiring. Think about where each line is going in the tunnel - e.g. the brake line is probably best running on the drivers side as
that's where the pedal and master cylinder are.

Thanks guys. What about securing to R axle? - welded brackets?

Live axle will require a flexible pipe section from around the diff area across to the rear axle. then you just need to treat the axle casing as you
have the chassis in your tunnel.

What have you guys built your chassis from, elastic? My brake pipes, fuel line and wiring haven't budged since I fitted them. Why should the
brake pipe wear through the electrics if they are clipped together so neither can move? Escort axles have tags facing one up one down to hold the
pipe. If you've ground them off or they've rusted away they should be easy enough to replace.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

In my case I was talking "SVA-speak" - Mr Inspector will give this sort of spiel when he fails the "dangerous bits".
In reality, if the lines are firmly tied together then the chance of problems is slight - but still greater than p-clipping them 6 or 7 inches apart,
as in my case.

How about 2 P clips on one fixing making a figure of 8 arrangement? I am going to try something like this for brake and fuel with the electrics in a
flexy PVC conduit on the other side.
I intend to use existing pipe brackets on the Capri axle with a 3 way bracketed to the top of the diff to pick up the flexi this way you can open up
the diff (Salisbury type) without disturbing the pipes and it should be easier to bleed as there are two branches to the rear drums rather than run a
pipe into one cylinder, out again to the other and only one bleed there.
Anyone see problems with this?
BTW what length of flexis are people using on a live axle set up and for front brakes on a book chassis?
TIA

That's pretty much what I've done but at the moment my two pipes are secured with cable ties. Looks like I'll need to weld a few
'tabs' on though. Pain in the arse - grind off my lovely paint etc. I thought the same as you, caber, about bleeding etc. hence a pipe to
each wheel.
I couldn't find the room on the rail to do the 'double clip' number. Not with the nylom P clips I've got, anyway. I figure
that the few wires coming from the rear will be a pretty skinny bundle so I plan to use two sets of staggered clips with B pipe and wiring on one side
- fuel line on the other
On the subject of pipes - what about routing the fuel line? Is it up the diagonal behind the seat and down again to the tank. Seems there is no way to
avoid at least some unsupported pipe.
