Fuel pressure 4.6 bar - is it filter, regulator or pump?

The fuel pressure on my car is 4.6 bar with the vacuum hose connected, and 5.1 bar with the hose disconnected.

It should be 5.0 / 5.5.

Is there any way of telling if this is due to the fuel-filter, fuel-presure-regulator or fuel-pump, please?
