Time For A New Fuel Pump?

[mayjamest]

I was getting really bad pump whine the other day. Pulled the regulator out, cleaned off the gunk and it seemed to fix the problem for about 2 hours. Got back to the dock and the pump started whining pretty hard at low rpm and idle. Replace the whole assembly or just the high/low pressure pump?

i'd say just the whiner based on what you shared
