I don't really see a problem with that tank sensor here at the shop, and they come installed on the new fuel pump whenever that one is replaced.
However, with the fuel pump hoopla going on now, and many and most after market ones not being compatible with the Saab engine and fuel system mapping, I would not be surprised if that tank sensor also have different settings in different GM models.
I have learned the hard way on older Saab and Volvo's using a Bosch EVAP purge valve (looks identical) that the flow rate is slightly different and that can trigger an EVAP code even though the purge valve is working.
