People do say the Walbros have a tendency to whine loudly. I've also seen recommendations for the TRE340 fuel pump, roughly the same price as a Walbro 255 and quieter. From what I've seen in the Impala service manual, the fuel tank pressure sensor is just for EVAP controls. I have removed it already, and the replacement seal that came with the new pump was indeed junk! Will definitely get an OEM one next time.
