I'm sorry I didn't catch this earlier, but how are you verifying fuel pressure during the run again? Do you have a sensor or a gauge in cockpit? It seems easy to just wire in a relay from the battery tied to the meth pump. You just need to tee into that 8 gauge to the meth pump and splice the fuel pump wires temporarily.

If you use taps you can just remove it. If the duty cycle goes down then its likely not the pump.
