If needed, I can bring a DC power supply and supply power directly to the pump but I was hoping there was an easier way to test the pump.
Thanks!

Run wire from the battery to the fuel pump. This the easiest way to for sure bypass the boat's wiring and the OPSS. You will find out whether the fuel pump has a problem or not.
