Running your own wires direct from the battery on it's own relay(s) etc will do quite a bit for you....I would just for curiosity's sake check what volts run to the fuel pump on MR2's, I have never had the chance to check those yet....ACC on and have your volt meter plugged into the terminal where the pump connects. If you have peak/hold functions on your voltmeter, then give those a go and see what the range is during just startup, idle after warm up, idle after a good run, perhaps if you can have a buddy check the volts while going full-boogey, LOL.
that tank is located in a messed up place btw

BTW if all voltages are ok / l make them ok is the Gen 3 pump sufficient ?
The wolfkaz site suggets that the OEM is good for 13 psi ?
