Non-mopar mechanical question?

Hey Everybody,
Quick question....the Fuel Pump on my 1997 GMC Jimmy went out and since I also have an Evap Emission DTC, I figured I'd change the Evap Pressure Sensor (aka fuel pressure sensor) at the same time and see if that resolves the issue since I replaced the gas cap.

Now here is the rub. I contacted my favorite local parts store and the lady (new gal) tells me she can't find the evap pressure sensor in the computer and so she cross referenced it with alldata and finds it. She then tells me it's giving her the same part number as the MAP sensor. Now, I know the parts look quite a bit alike and all, but are they the same sensor? I've crossed reference part numbers on about 10 different sites and haven't find identical part numbers yet.

Just figured if anyone would know, some of you old pros would. Let me know. Thanks.
