"Note" 'The following linked service manual is not for your engine size/model, just using it more as a general guide of how the fuel pumps tends to work... https://www.manualslib.com/manual/1087095/Mercury-40-Fourstroke.html?page=168#manual

The fuel pump is a diaphragm pump which is mechanically driven off of the rocker arm. The pump base insulates the fuel pump from the heat of the engine block. If the engine runs out of fuel or has a restriction (on the inlet side of the pump) preventing adequate fuel flow, the pump will make a "clicking" noise.
