Help me understand the fuel system!

Ok so I recently was given an old Holley electric pump. I plan on installing it in a few weeks and just wanted to make sure I understood everything before tearing into it.

I plan on installing the pump somewhere below the tank to help feed it. I install the regulator on the outlet side of the pump then just connect it back to the fuel line, correct? Then just run the electric for a switch somewhere inside the car.

Just want to make sure I am not forgetting anything.

I can't say I've ever seen the regulator right in front of the pump in the rear of the car. They are usually installed under the hood close to the carb. I suppose it should still work the same but make sure you are reading fuel pressure at the carb and not at the regulator if you put it back there. The pump can be mounted away from the fuel tank, as long as the inlet of the pump is (elevation wise) below the outlet of the tank. Not necessarily right under the tank if you get what I mean.

Oh and yes, put the pump on a switch with a relay.
