Plastic Tunnel Fuel Lines, I want to replace the 2 tunnel fuel lines in my 76 - 914 Options

[matchpoint]

I have my 76 - 914 engine and fuel tank out of my car during my frame off restoration. I want to replace the 2 plastic/nylon fuel lines in the tunnel with an OE product and not use the stainless or mild steal fuel line. I want to go back original and after 40 years of service I want to replace the plastic lines. Looks like everyone says go stainless but I want to go with the OE plastic.

Does anyone have a part number of a replacement plastic/nylon tubing of the same size as the OE plastic tubing. I think it is 7MM OD size. Auto Atlanta told me to just blow out the OE plastic lines and don't waste your time replacing. Looks like an easy replacement while the car is apart and all I need to know is a P/N of a plastic/nylon fuel tubing I can get @ NAPA.

Thanks

Whoaa......are we saying the 914 has AIRCRAFT QUALITY NYLON in their for fuel hose? Yeah, I don't think so. Looks like old ass plastic to me. I am well aware of the advances made in polymers today, but we are talking about the stuff already IN the car.

Jeff,

You need to remember that the "automotive engineers" always did answer to automotive bean counters. The 914 was a budget model. Premium products were not used in its manufacture. I am guessing the 914 has plastic lines because they were cheaper, not better. Certainly cheaper than stainless.

My 911s of the same era have metal lines. What does that tell you about what Porsche thought???

The lines are made from Nylon 12, 70-74, and Nylon 13, 75-76. This is an excellent choice as they are both usable with gas and alcohol. My 96 Audi A4 and 90 964 use nylon fuel lines (so do most cars) so do you really think it's just "old ass plastic" or maybe the best practice?

Can anyone expand on Nylon 12, 70-74 & Nylon 13, 75-76 as the fuel line tubing used to replace OE Nylon fuel line tubing on 914's.
