I don't know how much this will help but I'll try.I just did the Tbi to Carb swap and I got a holly 3 port regulator(1 in and 2 out)So what I did was,My fuel lines come out on the driver's side and I took the regulator pretty close to where the fuel lines came out,1 in,1 to the return line(usually the thicker of the 2)and ran a steel line around almost where the factory lines ran around the intake,I had to us a couple of small piece's of rubber fuel line here and there but for now it work's pretty good.Oh,and get a fuel pressure Gauge I think the holly is at 9 psi,I heard you don't need that much for a carb,but not sure..good luck!

All you have to do is get the necessary adapters to hook your existing lines to the regulator, the way I did it was to run my supply line in the side and return in the bottom port. Use the other open port for a fuel guage. Loosen the nut on top, and turn the allen head screw in for more pressure and out for less. Your pressure should be no more than 8 psi for Holley and 6 psi for edelbrock. Any more ques., just ask or e-mail me.
