As I mentioned in the other posts on the subject thats correct. Normally you replace the whole pod.



Try EBay. There are a bunch of GM OEM and Airtex fuel pump assemblies available for a lot less. Also you can try a salvage yard. Even if you could disassemble the fuel pump from the pod and put in an aftermarket such as a Walbro you may have problems with fuel intake afterwards especially when you get to low fuel in the tank.

BTW - Don't recall if it was suggested earlier but you can check fuel pressure at the rear fuel injector rail. There is a Schrader valve on the passenger side of engine injector rail. Alero pump puts out pretty good pressure. Typically it will read around 56 psi in the ignition run fuel pump prime position and 59 psi engine running and vacuum disconnected off the fuel pressure regulator. The test will either conclude the fuel pump is good or bad without guessing. Gauges only cost around $25 or so at Autozone.
