Just to be safe I would get a couple clear fuel filters put one before the fuel pump, and one before the carb, then you can be sure the line is good without wiping out your parts.

what had happened with my 56, is I blew through it until I just got air, but it was still scaly rusty on the inside, so it would slowly give up little chunks and powder rust which I could see building up in the bottom of the clear glass filter that was stock with the 56.

there is a chance that your line is fine, , I am going to do this same gamble on my 59 chev, because the line is such a pita to change, but if I clog up a couple filters , I'll have to change it.
