Your fuel filter is accessed under the car, a replaceable element, a blocked filter causes low pressure, but the Vauxhall system reports high pressure whether the pressure is too high or low, so the advice to change the filter first is good.

The in tank fuel pickup mesh on most cars is pretty course, it's only there to prevent large particles, pretty rare (but not impossible) to be blocked, more likely is a faulty fuel pressure sensor, if the car is running OK.
