Hi Lester,

Thanks for joining us and Welcome!! As to your fuel line question though not original I might recommend using copper tubing for that run. With todays fuels there is more moisture content in them causing regular steel lines which that originally was to rust corrode a lot quicker. S.S. might be alright though its much tougher to work with. Hopefully Jack, or Bruce might chime in here an expert opinion. Thanks again, if you get a chance please tell us about yourself and your project in the welcome mat section.

thanks for advice on using copper/SS.
However there is a decent supply of ethanol free fuels in the Atlanta area

The factory size is 8mm, but 5/16 works just as well and is more common here in the states. Never have had much trouble with steel on running cars, only ones that had the fuel system open and out in the elements.
PS: Name, please?

Lester, after two days of shaping and working with small SS lines I've learned and changed my mind it is pretty manageable to work with and I'll now be putting in a SS fuel hardline in my car. Glad you found a supplier.
