Researching fuel line options, but.....

[T and S]

I have spent hours trying to figure this out....
I have a 250 6 cyl with a weber carb. I am wanting to run the fuel line from the fuel pump (stock) to the carb all in hard line (5/16). The weber carb does not have an internal fuel filter, just a small strainer in the inlet.
I kinda decided on a in-line anodized fuel filter with AN fittings. I have found all of the fittings I need to use except the one to adapt a steel hard line to a AN fitting....
I did find an adapter fitting that uses a nut and farrow, but it says for use with aluminum line only.
What would you guys do here ? I have spent several hours searching and looking at fittings, I think I am missing something......

My limited understanding of this: For flare fittings, the tube side needs to be softer than the flare nipple side so that the tubing flare can deform and seal properly to the nipple. Back in my racing days, I'd see guys doing exactly what you want to do with AN style fittings made of carbon (black) steel or stainless steel. If you use stainless steel AN fittings, then I also suggest using stainless steel tubing or NiCopp tubing. And be sure to use Teflon if you thread this into an aluminum housing since stainless steel and aluminum can gall together over time. Not a bad thing if you never want to take it back apart and/or don't want it to leak though. Your options are more limited if you want to use mild steel lines, then carbon steel AN fittings are the best bet. In this case, check the Grainger catalog or something similar.
