8.1 Scanner / how to disable fuel pump

I bought the Rinda scanner for my 8.1s and I want to test a few things (coils and fuel injectors).
One requirement is to disable the fuel pump either by fuse or disconnect the wiring.

Can someone let me know where this would be on this motor?
serial 1G300326

Is it actually in the cool fuel unit?

Pull the power plug on the cool fuel unit.

I thought the 496 had 2, a pickup and an actual pump? I cant remember after I upgraded to the Aeromotive....

I thought so too which is partly why I was asking. A high pressure and low pressure one. ??
