That's 3mm ID x 6mm OD - Not the 2mm ID x 6mm OD used by Porsche...

It matters. Read this thread: CIS misfire

Miss ya too Rich!

As for the sizing, I just knew of a vendor who carried bulk in a variety of sizes - I didn't do a deep dive. Good to know on the 2x6 vs 3x6

Just bumping this to get some more info.
What are the ID sizes needed for the different lines on the 911 CIS ?

Injector lines look to be 2mmID and 6mm OD

What about the WUR to FD line?
Cold start injector?
Supply and return lines?

Any info appreciated.

I just replaced the line that goes to the bottom of the Accumulator. This line is the same as the rest of the lines going to the back of the fuel distributor.

M6X8 Polyamide. I ordered it from belmetric.
