As far as I know the pump plugin is ready to use.
Depending on the kind of pressure sensor you have you would connect the pressure sensor to the Arduino by:
connect the ground wire to ground
vcc to either 5v on the Arduino or to an external power supply
and the data wire to an analog pin on the Arduino
You will need to modify the Arduino firmware to account for the analog pin you are using and send the data to the Pi.
