Very nice write up! The only difference in my setup is I installed a larger fuel pump relay and larger wires to the pump. Use the existing fuel pump wires to turn on the relay. Twenty amps through the existing pump wires is questionable at best on my viper, it will definitely be dropping some voltage to the pump.
What did you end up using for relay and wire gauge to the pump? Glad I have come across this post, I was already questioning the stock wiring and it's ability to supply enough to the external pump.

I use this relay setup to run larger fuel pumps, expensive, but worth it.
