There's other people who've said those Facet pumps are of questionable reliability. You'd want to confirm what sort of volume the Facet pumps provide since there are many types. Point being is if you only ran one, you might not have enough volume. It could be that two were run in parallel to establish suitable volume.

I don't think you can go wrong with the Carter pump. It's a decent price at $80 and should provide plenty of volume for you. TEP says it can support up to 300 hp. Running one pump will simplify your system too. Because technically two pumps in parallel should have check valves on the outlet line, before they "Y" together, to isolate them from each other.

Be sure to check the condition of the existing braid hose if you plan to re-use some. Braid is just like any other hose- doesn't last forever. Braid actually makes it harder to inspect. Smell it and bend it. If its stinky or cracks when you bend it, it's garbage and needs to be replaced.
