Hi,
The manual only provides pressure with the engine off. See pic below for pressure specifications.
While the engine is running, the fuel pressure should drop about 5 psi, from the static prime pressure. If you snap the throttle, the fuel system pressure should jump up about 5 PSI.
Take a look at this link:

Based on the pressure you got with it running, it sounds like the pump is working as it should.
Let me know if this helps.
Take care,
Joe
