Crimps in fuel line to carb

My 318 2bbl Dart has an (apparently?) 1 year only Rochester 2GV carb on top. I have an obviously sticky needle valve that's causing the engine to get gobs of fuel, so I started eyeballing taking it off to do a rebuild.

The problem is, I looked at the hard line coming from the tank (on the passenger side), and it's got several kinks in it (4-5) as it comes up towards the carb.

Is this something that would be worth it to cut out, flare it, put a union in, and make a new piece of hard line to the carb? Or should I just leave it be? As long as I can confirm that's a fuel source (there shouldn't be a return?) I could also use that as an excuse to put a fuel filter inline.

I'm very new to non fuel-injected stuff, and to be completely honest, I'm trying to apply skills that I've observed from the family through some basic wrenching of my own.

Thanks!

Daniel
