Does anybody know the exact size/and fitting name of the fuel line that goes from the FP check valve and the accumulator. Are the metric pipe? German DIN? I'm trying to make a new fuel line

Sorry, that thread is probably only available to paid up members.
If you are referring to the main front to back steel fuel pipes they are about 6 and 9 mm. If you are referring to the flexible pipe from pump via accumulator to connect to the steel flow line to the fuel distributor can't help I'm afraid, I got hold of a new set for the Martini from ebay.

Just to educate the 5% of the world that live in the isolated and primitive countries of Liberia, Burma and the USA that wouldn`t know a metric thread if it hit them in da head, ALL the threads (except the oil filter) in these German cars are METRIC.
The accumulator thread is M14 x 1.5 as are most check valves, albeit with a banjo fitting.

Get the hell out, they use metric threads on a Porsche? You learn something everyday!
Look, I have been a technician for 22 years now. I am fully aware about metric thread. Like my first guess in my post was metric, of course. But my supplier asked a bunch of questions that I couldn't answer because I didn't have the size.
As for the decision on using the metric system.....nobody has knocked on my door and asked my opinion. But thank you for the info!

If you ask about steel pipes under the car.. you can replace it with copper 8mm - return pipes and 10mm feed.

I reused the existing fittings and had new flex hose installed. Otherwise the fittings are metric inverted flare, very rare and hardly used in automotive circles.

I beg to differ. The seatbelt mounting holes are most certainly SAE as well, as discussed at length elsewhere on this site.

Apparently so, although I have never checked personally.
Ironically, I thought of that point after posting, and received psychic vibes that it would be corrected.
@OP, although I am using some AN-6 fittings on these same threads myself in the RETURN line, being HP fuel line will NOT suggest anyone do likewise. Similar size but mismatched thread and also 37* Vs 45* flare angle. Suggest reusing the original fittings as well or sourcing the correct metric adapters from your favourite supplier, Summit, whoever.
