I personally have serious concerns with the electric fuel pump. Not so much as making it work, but making it work safely.

Concern #1 is too much fuel pressure overpowering the needle in the float bowl and causing excess gasoline to spill out the vent hole. .....snip.....
Concern #2 is control of the electric pump – provided we find one that will work. We cannot just turn it on and leave it on. We need a way to control the pump so that it will provide initial pressure when we want to start the engine and then transfer control to something that will only allow the pump to run when the engine is running. Without this failsafe, if the engine were just cut off, the pump would still be supplying gasoline. If this gas was leaking, we could have a dangerous situation. .....snip.....
Watcyha think?

With your concerns in mind plus these concerns:
#3 - locating fuel tank "outside" a home-made sound enclosure.
#4 - not enough room for the stock tank to fit "above" the carburetor for gravity feed.

I read a post (not sure if in this humongus thread or somewhere else) relating to the following:

Why not build a small fuel tank that can fit above the sound enclosure that has a return fuel line back to the source fuel tank. The outlet for this return fuel line would be near the top of the tank. Gravity feed fuel to the carburetor. Then any fuel pump can be used without concern for over powering the needle valve or auto fuel shut off for safety reasons. Any excess fuel would just return back to the source tank.

EDIT: While reading this after posting it, I think I answered my own question. The problem would be how to get a return line back into the source tank. Forget this post .... :S
