I thought on the 928 Porsche only used one size tube - certainly from 84 onwards.
Part number N 020 139 1.
Do the two different sizes enable coverage of all the Porsche types?

Sorry Carl - I went back and read the description on the web site - this is a cover all kit - I understand.

I found that the tubing on my 91 was larger than the tubing on the 85... It was easier to make a kit with 8' of both than to try to figure out which MY car might have which.

On my intake job recently, I found that the short rigid line from the throttle body to the 5-way under the air-box (mine's a manual gearbox - auto's have 7-way I believe?) is a 4mm line, but the four lines from the 5-way to other actuators were 3mm.

It was only that one stretch of about 30cm that was the larger diameter. I used silicone vacuum hose to replace all my lines - with 2.5mm thick walls so they're strong enough not to collapse under vacuum.

Carl is selling a path to the void, a path to guide the flow of nothingness, with support, if you prefer.

Excellent product. How philosophical, but useful at the same time.
