If you want quality and reliability...........get a Weldon fuel pump. My Aeromotive 1000 (external) (I know your internal), just crapped out and died wed. So I was looking around and my shop guy here in Arlington said if I want something that will last and can take the power I need a Weldon pump............
If your supercharging and want serious power for your $ you spent, you might consider a returnable fuel system so you can run an external pump and get higher psi (fuel), boost, and timing.
What it takes...
New 5.0 gas tank 60$ used.
Fuel lines (non braded preferred) $ expensive...200+$ 8n-to engine, 6an return to tank, 10an to pump from tank.
Weldon EXT. pump...350-700$

Fuel rails -200$
Fittings-100$
