66 Dart GT HT Whatsitgonnabe?

Okay, I've researched the carb installation a bit. I've got a Carter AFB 9755S, identical to this Edelborck (but with manual choke) (see pic below).

So the fuel goes in via the fuel inlet (of course). What about the return line? I'll be using the stock pump on the 360 for starters.

And the vacuum ports, is it a good idea to use the ports on the carb? The one marked MANIFOLD VACUUM for the distributor and the rear port (POWER BRAKE PORT) for the brake assist drum?

Or should I use the ports directly on the intake manifold (Edelbrock LD4B)?

Anyone?
