Copper fuel line

[philburch]

Rebuilding car after having chassi repainted , copper fuel lines are badley pitted and need replacing . My first question is , can the one which comes over the bell housing be made a bit longer to aid changing the flexible hose easier in the future , or is there a reason it finishes were it does . Second question , Have seen some copper pipe with a plastic sleeve covering it , anybody see any problems useing this as it would stop it corroding in the future .

Yep, run the copper pipe as short or long as you like. Like you say bringing it into the engine bay makes for easier changing of the rubber hoses in the future.

Cant help with the plastic coated ones tho.

Lose it and go braided line all the way down IMO

Not sure about this, its my understanding that they still have rubber hoses under the braiding, the problem still remains of heat effecting the rubber, I would go for copper for most of it and only use braided were I could change it easily.
Perhaps consider spraying the copper pipe with a lacquer.

Plastic coated sounds like a good idea to me as long as the cut ends don't let water creep down between the 2 layers.

The plastic covered stuff is used for oil fired central heating boilers as you an bury it in the ground, but that will be a bigger diameter.

Yes good point. Remember there isnt much space between the chassis and body where the copper pipe runs.

I replaced mine and ended the copper pipes shorter than standard, down by the gearbox, easily accessible from under the car

Thank's for the replys ,think I will just make the copper pipe a bit longer so it will be easier to change the rubber one when needed . Copper pipe with plastic sleeve is advertised as 8mm o/d which is the same as on the car , if it is for central heating oil maybe not suitable for petrol.Why is the pipe to the carbon cannister all rubber and not part copper like the other two.

I think you will find the plastic protects from the moisture etc in the soil, the copper pipe will be the same and fine for petrol.

Had mine run in stainless steel

I did this when I replaced the flexi pipes on a Chim for a mate.
It certainly makes life easier having the hard copper line end down the left of the gearbox where you can both see it and get both hands to it.

It always helps if you can get both hands on it.
