Running 'Stuff' Through the Trans Tunnel
scootz - 22/2/11 at 06:38 PM

My car is already road registered, so IVA intricacies are not essential. That said, I want to be sensible, so there won't be anything overly daft - I want it to remain MOT and C&U friendly.

Can I run the following through the trans-tunnel:

Steel braided fuel lines
Steel braided brake lines
Electrical Wiring in a... yep, you guessed it... steel braided hose

Cheers

Yes why not all my brake / fuel / wires run though the tunnel

of course lol why wouldn't you?

As safe a place as any, if not safer than under!

Having said that, I'd probably want to make sure you've got a prop retainer of sorts (regardless of whether you're running pipes/wires down there).

You can however I would question using steel braided, fuel hose can weep, brake hose can flex, steel or copper fuel line and copper brake hose is more durable and a lot cheaper.
Some form of protection incase the prop let's go, I know people that this has happens to.
I don't know why more people don't use a false tunnel top and run it all through there, easy to get at.

Dunno... was sure I read somewhere that there were rules and regs surrounding what you ran through the tunnel and what you ran it in!

I could of course be talking a load of pish... it does happen from time to time!

nah, the iva just says it has to be fit for purpose basically, and adequately supported.

so as long as its brake hose, and fuel hose, its spot on

Thanks people! I'm off to ebay!

Just questioning the use of braided hose. Why use a component that is more expensive and has a shorter service life than copper pipe, when the benefits of flexibility are not necessary?

I have used copper pipe and then fitted it inside thick walled neoprene tubing sealed at both ends. This has the corrosion resistance of copper, and also the impact and abrasion resistance of neoprene in an exposed location. And its neat and cheap.

I hear what you're saying, and agree you're probably right... but I just think braided looks better.

I don't see the worry with braided hose's. They've been used on bikes for years, they're only small runs too. They can flex/move and are easier to work around. Plenty of pukka race cars at goodwood have fully braided systems so they can't be bad

Do a search for braided fuel hose, it seems that it is not a case of if it weeps, but when

Again... you're right. But Hedgehogs like bling too!

Is this not just unneccisary weight aswell?

Mind you just have a cr@p before hand and that will off set the cable weight!

I'd only ever use it in the braking system. You get what you pay for with hoses remember too!
