Don’t use steel braided rubber. The old hose gets eaten by ethanol fuel. It’s funny I had the same steel braided rubber hose 20+ years in the race car using leaded race gas. With unleaded 6-8 years at best.

The only issue I have ever had with braided lines is with some brands fittings having the anodized coating fade over time when subjected to a lot of engine heat but never any leaks, just use quality fittings and an installation procedure that works.
Or, properly tightening the house brand, China boi shizz breaks it....

-8 AN feed in the wagon with a Corvette regulator kicking -6 AN back to the tank; and a -10 AN feed in the MCSS with -6 AN return (PTFE).

Works fine, just keep it nice and secure so it doesn't chaff against the frame or body.

Had that happen in my old Turbo Buick, it made a mess. I believe that car had a -10 AN feed and -6 AN return.

So, yes. A lot it seems.

I'm thinking about it. Gonna be pulling the body off here in the next week or so and I'll be running the lines before I put it back on.

Here's where I'm at, I have a stainless hard line bent to match the factory bends with -8 ends on it. I had it made by inline tube a long time ago. I figure it will be a miracle if I am able to get it in the car where it's supposed to be. If I cannot get it in I'll cut it in half and flare the ends and hope I can get it in in two pieces. Just got in from the garage and I pulled the 5/16" original line out in one piece. Obviously the new one is much bigger but I'm not giving up yet. I will use ptfe lines at each end which is impervious to any fuels including nitromethane. I really really really do not want to lift the body to install the fuel lines. My plan B is to use a proper flexible hose. Thanks for the help
