I found an aftermarket replacement blower which works on the FPX Elite 36. The FPX part number for the blower is 98500780, but it was hard to find that part and was quite expensive. I was able to find an equivalent blower, it's a Dayton 1TDR7. Dimensions are identical for the mounting screws and opening. I took the metal baffle/flap off the old blower and installed it on the new one. Photo below is the Dayton blower installed in the original housing. It's a pretty easy DIY job.
