Maybe, depends on what motor?

If its a Merc carb motor and gauge is accurate then all good

That's normal, a mechanical diaphragm pump will pulse like that or even a bit more. An electric can also see a bit of that

What he said. Mechanical diaphragm pump will have pulsations in discharge line. It’s doing exactly what it should do
