I used my Durametric tool to connect to the DME and clicked on the "Actual Values" menu under the Engine Management tab. If you scroll through the list (there are lots and lots of different sensor readings) you will see both "Fuel high pressure set point" and "Fuel high pressure actual value". Check the selection box next to these values and they'll be displayed at the bottom of the screen. The setpoint is what the DME is requesting from the pump and the actual value is what is being delivered.
