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

Jeff,

I just replaced my OE metal/plastic lines that run thru the tunnel and the plastic lines that run from the below the engine shelf to above with SS lines from Tangerine. The leak I experienced before the change was above the engine shelf where the clear plastic line was inserted into a rubber line to feed the injectors. Seems like that OE clear plastic line kept shrinking and I had to keep tightening the clamp to prevent leakage. I think I was really lucky that I didn't have a fire. My car is a '73; I'm not sure if lines in a 1976 are the same.

So my question is: do you think I made a mistake going to SS?

I have a chemistry background. There are a ton of different plastics out there, each with different characteristics and interactions with the various components in fuel. Lifespans will vary. SS, on the other hand, can sit in any fuel with any additive(s) for 1000 years and will not degrade one bit.

I can understand the desire for OE AMAP. It's kind of cool to have a timecapsule; I think it's one of the things that binds 914World members. It just seems to me that SS is WAY more durable (and therefore safer) than the OE lines and they are not that expensive or difficult to install.
