Fuel lines: info for install a Cartech FMU...

[nuvolarossa]

Hi,
I have a M44 318is that will be S/Ced with a eaton m62 with a custom setup (no Midnight Autowerks, no DASC). At the beginning I would use a Cartech FMU. And here is the "problem"... there are 2 versions that I can fit:
- 2025 for aftermarket turbo and supercharger system with 1/8 NPT fuel lines;
- 2027 for aftermarket turbo and supercharger system with 1/4 NPT fuel lines.

Premised that I didn't use the inch measures (I'm in Italy), so what is the correct measure of the lines? 1/4 or 1/8?

thank you
reply fast that I want to test the whine of the supercharger
bye
