Pump to Carburetor Fuel Lines, what are you all using?

[CastIron]

So I think I'm going to run a 5/16" steel line with inverted flares from the fuel pump to an adapter to change to AN -6, then into a swivel coupler and onto an Edelbrock fuel line/filter. I don't like to use that many joints, but I can't seem to find a fuel filter that uses 5/16" fuel line (inverted flare) on both sides. Most aftermarket filters are AN -6 or for rubber hoses. I'm trying to avoid the use of any rubber between the pump and carb.
