Fuel Line replacement

Does anyone have a schematic of the fuel system in a 72 MFI car?
I don't like the look of all the frayed old fuel lines running around the engine bay. Do I need to buy replacements from Porsche or can I get them made up somewhere. The feeds to the MFI pump and then the cold start system worry me a lot and while the engines out I'd like to replace them. Anyone else done this job?

I had the job done last autumn, and the hose was available from Porsche and it was not expensive. Like you, I was worried about dried out hoses (mine were 37 years old).
I stayed with OEM replacment stuff. It doesn't look as neat, but it works.

Thanks. Those Earl pipes look pretty snazzy.
Dom, how much did you change? I'm thinking everything from the fuel pump onwards.

All the flexible tubing in the fuel system. We even put some Kurust on the tubes that were rusting.
Plus the whole brake system and the whole oiling system were changed. I also put on turbo valve covers, now expanding tubes, two new chain tensioners. The whole shooting match.

Don't forget the hose around the fuel tank, fuel pump and to the piping system.

Anyone know the inner diameter of the cold start fule lines that run around the stacks. Its the only pipe I need now and I forgot to measure it while I was with the engine at the weekend.
