They didn't entertain the idea of pulling power through the fuse box cause it could create "electrical noise"; I can see that with respect to the ecu but I think if I power the fuel pump through the fuse box I could solve most of my issue...thoughts?
Well, I'm guessing the fuel pump, and maybe the ECU, are currently getting power directly from the battery, thus pulling all of their power through the ammeter .

Well, assuming the fuel pump has its own dedicated fuse, I think if you power the fuel pump from the hot feed INTO the fuse box, or at either end of the alternator "Bat" wire, you bypass the ammeter, with power going directly from the alternator to the fuel pump ( whenever the pump relay is closed ) . Then, all the power through the ammeter is only going to recharge the battery. Yeah. I think this may work.
