Can a bad fule pump make the same noise as a loose valve on a Yamaha 4 stroke?

Hi

I have a 2004 F75 4 stroke that is making a tapping sound above 3500 rpm at about the same place the fuel pump is located on the valve cover it sounds just like a loose valve tapping the engine was running quite and all of the sudden it has this noise. Any Help would be appreciated

Thanks Tim

The fuel pump will make a tapping noise if not completely primed with fuel.

Is it bad ?

Is the tapping noise of the pump bad for the engine or the fuel pump it self?

Thanks.
