Re: Fuel Pump Noise

Normal operation , the pump would soon build up max pressure and hold it,clicking once in a while as engine takes what's wanted or it's internal spring loaded release valve leaks back.If it clicks fast ,it's either moving fuel down the line or back-pedalling internally. When I use it for filling day tank(no line blockage) it whirred. When I ran it direct to carb of stove the occasional clicking told me rate of burn . Same applies as an engine app;ication. Think solenoid pushing a spring loaded piston with leaky valves.
