I replaced all the fuel lines last year and used the Porsche O.E.M. parts which took a couple of weeks to ship over from Germany. The hard lines didn't appear to be stocked by anybody when I was looking for them. So plan ahead. The supply hardline shows up as two pieces on the schematic, but was one continuous piece on my 86 951 when removed.
On a humorous note, the supply was leaking at the crimp in the engine compartment, so I clipped a silicone oven mitt around the line to catch the drip on the way to the shop. Not the best idea, but it worked for the five mile ride.
After I replaced my lines my fuel rail started to leak at the seams. Got a LR fuel rail, aside from the injectors not staying in when removing the fuel rail, its pretty awesome. And you don't need that dampener fuel line with there dampener setup.
