Model E150stlcca......serial # 1820335. The motor is a 1988 150 XP

I am getting an intermittant buzzer. I found an oil leak around the vro. I don't feel like spending the $$$ for a new VRO. If I disconnect it and the alarm wires will the restricted fuel buzzer still sound off? Do I have to get a stand alone fuel pump or will it work as is?

Thank you
