Replacing Plastic CIS Lines with Late Metal Lines

[CountD]

Searched the forum and was wondering if anyone has replaced the plastic black injector lines to the later metal ones from a SC, etc. The metal looks the way to go and would like to go this route if anyone else has done it. Let me know, Thanks.

BoxsterGT makes lines from modern polyamid - search for him

no affiliation BTW

You can buy new factory cohline ones for about $120 a set from gowestyautoparts.com
Wayne doesn't seem to have both sides available.

I have replaced the black plastic lines on my 2.7 (long gone) with later, metal lines from an SC. Worked great.

Once again, thanks to all who responded. I really appreciate it. I will check the availability of the metal lines as I am paranoid of the 35-year-old lines, or will replace with new.

The thing is you still have a rubber/plastic line to deal with even with the metal lines. The line for the WUR is half metal and half rubber, and is of course "NLA." I have a set of metal lines I was going to swap but in the end I just did a new set of plastic because of the WUR. But either way you want to go.

Thanks, great advice. I just want to go safe. I looked at the price of the plastic and it's not too bad - the 4-6 cylinder are about $12 more a piece, but for $150 for the set it's great insurance (and piece of mind).

I have just recently started doing CIS systems after so many requests for the Polyamid tunnel lines. Been doing Metric Fuel & Oil Hoses for the other Porsche models for many years.

Presently, I make up the Polyamid injector lines and charge $20 ea w new fittings. The combined Fuel Filter to Fuel Head to WU reg assy must be done on a fixture and on your fittings. For this I charge $50 with the correct Polyamid lines.

I also sell this Polyamid line in bulk, as well as any individual Metric fittings anyone may need.

For this or other Porsche lines or hoses, please email me. I would be happy to help.
