I found a small leak at the point where the gas line screws into the regulator. I tighten it down as much as I could using pliers and that didn't resolve the issue. Is it ok to use teflon / plumbers tape on the threads in this connection?

It's usually a flare fitting, and you don't use teflon or dope on flare fittings, the sealing surface is not the threads, it's the flare. Further, get a wrench to tighten, pliers are pretty much useless.

Yes you should use the little nylon washer when connecting a flare fitting when there is metal on metal (but not for example with the ball lock disconnect flares that have the built in washer). I've always seen regulators come with a barb fitting though, you are not talking about it leaking where the shut off valve screws into the regulator body are you?

?????.........The one threading into the regulator body, ( pictured, wrapped in tape), is a flare fitting?
I could see, the one below the valve being so.

What?
The OP was using his own personal vernacular when he said "where the gas line screws into the regulator". Apparently he really meant "where the gas line swivel nut screws onto the shut-off valve", and he must not have stuck that little white plastic gasket in there before assembling same.
We're good. I think.
What you're pointing at is likely a straight pipe thread, I'm not sure there's a taper there or not...
Cheers!

Never seen a flare nipple going into the regulator body!

Yeah, I kind of went by the beat-to-hell appearance of the swivel nut and assumed that was the connection the OP was talking about. As you say, I think we're good.
