I have made new fuel lines from Kunifer but I am just not that happy with the way they sit. I was contemplating taking them off and replacing them with stainless braided hose ( goodridge). Has anyone done this and is there a good reason why I can't use 3/8 th pipe for both sides rather than 8mm and 10mm.
 
Whats wrong with how they sit? I made fuel lines for my Golf with it, not factory straight but good enough.

We made new fuel lines for son's project 951 from copper lines. We wanted to have a factory look, so first we painted lines with 1K primer. After that we added green oem style color (2K epoxy paint) the local paint shop mixed for us according to sample taken from original old line. Then we put clear heat shrinkable plastic cover on lines. Most likely these lines will be good for next twenty years
 
I just feel that they sit a bit awkwardly and the corners around the area where they come up the inner wing to the engine look like they might rub. I went today and priced a set of stainless braided ptfe high pressure fuel hose and I am going to go down that route as I feel they will be both maintenance free and easy to fit and get tidy looking.
 
Hi Colin, Would you mind letting me know who your getting to make your braided fuel lines and also an indication of the cost? This is a route I was going to take but I've not gotten round to it yet. Will you get the pipes made to fit directly to the fuel rail & filter or use the existing Porsche flexi pipes & just replace the hard lines? Thanks, Alan.

Never mind 20 years, with that kind of treatment those lines will still be intact when our sun is a white dwarf. There was an interesting posting recently about the use of high pressure nylon lines with brass end fittings - if the poster reads this, did you ever fit them?
 
All I had made fuel lines off a couple of winters ago - took the full lines to Paul at Spectrum hose in High Wycombe, he cut out the rusty sections (over the rear axle) measured up and made SS flexi lines for the rear and also the front end where the they go int through the wheel arch. These then fit onto the original steel lines with compression fittings. Paul and the chaps @ Spectrum hose are used to doing every type of hydraulic/ fluid containing line under the sun - 3 - 5 bar fuel pressure is nothing. Like Pirtek they're using to dealing in 100's of bar ! IIRC the total cost was about £80 all in = great value ! Chris
 
I got a local supplier of hydraulic hoses to make them for me.I have kept the flexi hoses over the engine but got the rest made in Stainless braided ptfe pipe. They cost me £140 including the fittings etc. I recon that's good value considering they will be good for a long time ( maybe not as long as Oli's nuclear resistant ones) but 20 odd years any way.
 
Fitted new lines on Sat. apart from letting the beam down a couple of mm to let the fittings through it was easy and took me less than an hour. They look so much better and should be maintenance free for a good few years.

You should then install additional clips/supports as they dont span the same and will sag/vibrate.
