fuel lines and cable routes?
mongrelwestie - 10/1/08 at 08:33 PM
if my fuel lines cross the transmission tunnel, will my wiring loom have to switch to be oppersite? or can i run them lower along a different side??
whats the rules??

As far as I understand it, fuel and electric cables must not be run "together". I would think you can run them where you like as long as
there is a reasonable spacing between them - six inches min say ?

i thought that might be the case, so as long as i keep them apart i should be ok

My fuel/brake lines and loom run right next to each other and my car passed.
As long as they are individually clipped to your chassis (not tied to each other) then it is ok.

from section 15.2
quote:
checks all fuel system components and fuel pipes for
* leaks
* security
* suitability of design/construction
* positioning
components should be positioned such as to minimise risk of fire in the event of a fuel leak
similar section to one highlighted appears for wiring which I ain't typing out 
so I would say it doesn't matter what anyone else has done that can be conisdered iffy and passed but it is at the examiner's discretion as
to whether your set up is ok.
So if it were me, I'd put the fuel under the electicals since unless you've done a turtle, fuel isn't going to leak upwards.

that where my thoughts 2 until i realised that a small hole with pressure will spray everywhere...
put the fuelline in an extra flexible tube of plastic. then you have added some extra protecion etc. etc.

good point - let us hope the SVA inspectors never see this otherwise all cars will fail

How can a loom ignite petrol (vapour)?

I think the implication is that an accident which causes damage to a fuel line be likely to also damage wiring in the vicinity and thus create a
potential source of ignition.

Well. If the accident damages the fuel line and the loom, in the transmission tunnel, I think it's safe to say you're in huge trouble
anyway!

What happens if the propshaft lets go?
I think that they're more worried about one thing rubbing on another - e.g. the loom rubbing on the fuel pipe. If you get it just right, you can
wear through the fuel pipe just as the wires' insulation has almost gone...
I worked on the basis that if they're separated, and you can't pull one against the other, then you'll be OK.
