Fuel System

[mitch22]

My current fuel set up is from the Vortec kit with the T-Rex 250gpm pump mounted outside of the tank. I also have 42 lb injectors with stock rails. With the current changes being made to the car I know I need to upgrade the fuel system. Would this include
1000gpm pump.
Intank setup
65lb injectors
Upgraded fuel rails.
Trying to figure whats next.
I think its the fuel and a T-56 upgrade
Any thoughts
