Routing fuel pipes.

[Pink_Floyd]

I am about to replace the fuel pipes from the rear to front on the chim before I put the body back on. Have people that have done this followed the factory route? Gone a better way? Also have you used the same pipe? on the passenger side the flow is 8mm copper and the return from the carbon canister is 7mm rubber.

If I was replacing fuel pipes then I would use solid stainless steel Ø8-10ID tube for both supply and return with short lengths of easily replaced rubber either end to seal onto pump & engine.

The tunnel does get very hot as well so moving the fuel line run to the out-rigger / sill area would reap benefits in terms of cooler fuel / more power.
However this has to be weighed up against the difficulty of a new run and in a crash the fuel line is more likely to be ruptured.

This is the way the factoty routed the pipes

I was planning something like this

But using copper all the way. Is there any good reason for routing them as in the first photo. As you see the body is not on so maybe there is not enough clearence between the body and chasis to route it over the rear chasis member.

While you have access to the fuel pipes, could you give me an idea of the total length all the rubber hoses are and how many hose clips are needed to change all the hoses? also is the hose all the same size?

I intend to do the rubber fuel hoses on my car at Christmas and want to get the bits ordered beforehand, but am working away from home at the moment so I don't have access to the car to work it out for myself.

Thanks

The section in the pictures is the rear passenger side. Would it be possible for someone to remove their passenger rear wheel and have a look to see if there is any reason why I cannot route the pipes over the rear chasis member. It could be that the body tub touches the chasis there and so there is no room. This is on a 1998 Chim, although I don't suppose this bit of the car changed much over the years.
Be really good if someone could take some photos and post here or email to me.
Thanks inadvance

just nipped out for a look and i can see no reason why you couldn't route it over rather than under. there's certainly nothing that will foul or rub the pipes just there....

Thanks for that.

Looks to me as if the routing in both of those pictures has the potential to trap the hose between the chassis and body. I'd much rather see it routed inside the tunnel, in the top corner up well away from the exhaust and moving bits.

That is how it was routed when I took the body off, don't know if they are all routed like that or if on different days of the week they were in different places. Did cross my mind to put them up inside the tunnell. Being the side of the rail that they were I would assume that they were protected from the heat of engine, exhaust etc.
All comments welcome about better routing.
The copper (green coloured) pipe is the petrol to the engine, the rubber one is to the carbon canister. I was going to replace the rubber one in copper. The copper pipe under the top of the tunnel on the other side is the return pipe to the tank, i think that you can only see the tie wraps in this photo.

Pic of where they were when body removed

On the V8S they are up in the top of the tunnel - they are also rubber front to rear. My old pipes (1992) were in pretty good nick when I removed them, they are well protected up there.

Best pic I could dig up.
