How do I check if the fuel pump is working?

How do I check the fuel pump is working e.g pressure without a gauge?

Given that the pressures will be (from the tank to the pump 2 to 5 bar) and from the HPP to the rail/injectors 200 BAR on cranking over. 300 BAR on idling and anything from 1200 to 1800 BAR on running, I would suggest that the only way to check is with the correct equipment.
