Now that I am approaching 97K on my '98 E1 SVT, I decided to replace the WP for PM (my son is now driving it) & purchased a Prestone (GMB) pump with an iron impeller. However, after reading this post I'm going to get a Ford XS2Z-8501-EA come Monday & return the Prestone.
Thanks for the informative info!!

your not gonna get much pressure out of the water pump if you just remove that, lol. that is what keeps the impellar sealed up to something (as close to sealed up as it can get without rubbing that is) replace the pump

The pump on my '98 seemed fine, but after having one fail explosively on my '96, I decided to replace it as PM while I had a bunch of other stuff apart in there... At 110K I figured it was probably on borrowed time anyway. I took the pump out of the housing, and the restrictor plate just fell out. It was all scored up, so obviously had been riding on the impeller for some time. Oddly, it didn't make any noise that I could hear with the engine running. The whole Motorcraft pump assembly is available from Amazon for $90 right now, and come with the two big hoses attached. On my '96 I just replaced the impeller part and it was fine, but I 'm really glad I just went ahead and ordered the entire housing in the first place...
