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 |

Three reasons Porsche may have used plastic fuel line in the tunnel. 1. Cost 2. Easy to handle at assembly 3. Porsche was able to eliminate 2 splices of rubber fuel line hose in the engine bay that would have been required to connect a metal line from the tunnel and a shorter metal line that runs up through the engine shelf at the battery tray. This would have required 4 rubber to metal connections in an engine bay. More risk of hose clamp fuel leak in an engine bay. By using plastic Porsche has a longer continuous plastic run without adding unnecessary splices after the firewall into the engine bay.
My car 76 - 914 and has 2 long runs of OE Black Nylon/Plastic Polyamide that is 8mm OD and 6mm that are about equal length. Does anyone out there have a P/N and source where I could purchase 25'? The one supplier so far that I have found is Bel-Metric. They offer a German product mfg by Cohline that they sell for $8.25 per Meter. Thank You |
