Any one use the compression fitted fuel line ends to adapt the pipette on the fuller tank to a PTFE 6AN fuel line?
Feed back and experience appreciated.... |

You can tap the threaed nipples on the tank1/4 FPT. Install pipe threadcto 6an. You loose the sock filter in the tank. Some VW parts suppliers have one of the nipples with 6AN fitting.
I have considered adding an externally industrial cleanable filter outside the tank. |

I did this. I converted 911 Carrera hardlines to the engine bay (near the filter by cutting the pipes square and installing 6AN PTFE lines. Holds well.

Yes, did this using -6AN fittings from IIRC air-cooled.net to the tank (no longer in business) and installed PTFE fuel lines and fittings.
Also, Chris Foley of Tangerine Racing can TIG weld AN fittings on the stainless fuel lines he sells (take your pick, front or rear - we chose rear). Edit: Actually and thinking about it some more, don't think AN fittings welded on the stainless fuel lines will pass the front/rear firewall without some opening up of the holes. Which is why we only have AN fittings on the rear of the fuel lines. |

Seems like you have a better path now but just in case you have future need there is only one place I know of sells these metric compression to to 37 degree adapter fittings... FAV Fittings FCF/MCJF/5I-8T https://favfittings.com/instrument-fittings...onnector-jic-2/ They are a real company. (IMG:style_emoticons/default/laugh.gif) No idea on what the lead time for this kind of stuff is though. |
