Oh and yes you're right, I was going to leave them hanging without clipping them into the existing mounts, silly me!

I'd forget using rubber, besides which, how are you going to join them at each end of the system? There are plastic ones available made for the job with all the right fittings too, can't remember the name of the product, but mrpat on here has used them on his 80 quattro and they look superb.

Existing mounts are spaced half a meter between each other, however, unlike copper or steel, rubber is elastic and won't hold shape. I have plastic fuel tank vent line on my A90q, similar to ones in central locking system, despite it's plastic not rubber, it still has problems with turns, where it requires a couple of additional fasteners, fortunately I can fasten it to copper fuel lines.

What's the reason why you don't want to fit proper copper lines? Are they too cheap or too durable for you?

To be honest, it was braided plastic ones I was planning on using, cutting the existing ends of the copper ones about 4 inches from their ends and threading the plastic pipes over before securing with Jubilee clips. I would be interested to know where i could get a made up set of plastic ones.

May I ask why you appear to be trolling me on here, do you have so little going on in your own life that you need to come and slag me off?

If i could find a new set of copper lines, i would use them. As it is i dont have the time or space at the moment to bend and make up my own set from scratch, hence why I'm looking to use the next best thing i.e. plastic braided purpose made fuel line.

If you dont have anything useful to say, please refrain from saying anything.

Due to the fact that the fuel is being pumped at such high pressure,securing rubber or plastic pipes with jubilee clips might be okay for a temporary, or a get you home repair, but not a good idea long term. Potentially a recipe for disaster.

I'll find out about the plastic lines for you.

I'm sure MSH's intentions are to give the best advice, and I have to agree with that advice replacing the pipes with 5/16ths internal bore cupranickel is the way to go. I've seen an attempt to do it in plastic and the car ended up coming to the workshop to be put right.

With a ramp and the right equipment (flaring kit) its generally 4-5 hours to remove the old system and make up/bend/flare and fit a new set. But dropping the front sub-frame helps as does removing the O/S gearbox mount. Its not an easy job if you are working on the garage floor.

IMO you'ld be best to patch the leaking pipe in rubber for now and get the job done properly when either you have the time and equipment available or get it done professionally and then you can forget it.

You're right about that "so little going on in your life" portion, as I currently have a prolonged vacation but my A90q is waiting for weldor to do some small things, so I have nothing to do. Also, it's good that we're both thinking similarly - it also appear to me that you're trolling the rest of us by willing to buy fuel lines made from wrong material

Otherwise I agree to Roger on all points, apart from the need of flare kit - I bought my lines in Hansaflex hydraulic parts store and they did that on one end of each line for additional fee. Actually it wouldn't be even 4-5 hours, if doing quickly, and RHD UR probably is even easier to bend the lines in place, as the biggest problem for me was the place below battery tray, where, obviously, in RHD cars is brake master cylinder located. Garage with pit and one friend in it recommended.
