My question is, do I have to run a return line to the fuel tank or can I just install the pump and be good to go.

Youll have to run some sort of a regulator if you dont have one already. Most electric pumps will push way more than the needle and seats will hold.
Something else to consider. Try backing your idle screws out just a little to give it alittle more fuel at idle. Your strictly on the idle circuits at idle obviously and if you set them when the motor was cold they may not be rich enough. Back them out a 1/2 turn and see that that does.
Just a thought.
