Another check is to remove the outlet pipe from the tank - it is on the passenger side tank module, and see if you get the same flow rate from the inlet pipe to the UBP as you do from the tank outlet. If you don't there is a partial blockage somewhere in that line.

I'm embarrassed to admit that the clear protector on the inlet was indeed stuck in the hose of the ubp! Removed and job done pump is now whisper quiet and car runs once again.
