Carb to Fuel Pump Hard Line [Leak at Fuel Pump]

[Rich72C10]

My current hard line is a bit tired from previous owners not likely using a flare nut wrench and also looks like the line has been bent around a few times too. I bought a hard line from Summit Racing, actually this is my second one and the best I can get it is perhaps 2~3 drops a second of leakage. I tried the lapping method for over 30 minutes, never got it better than the 2~3 drops a second. Both of the lines I got from Summit Racing acted the same way.

So I am giving up on Summit and have ordered one from GMCPaul's and put the old one back on. I thought I bought the steel line but I see from my email confirmation I got the stainless steel one.

I know these lines do not take any sealer, tape, dope, etc. Any other tips out there for when I get my GMCPaul's line in? Should I also reach out to GMCPaul's to switch the stainless steel to regular steel one?

Thanks for helping me NOT setting my trunk on fire
