I see several possible advantages to the dual pump setup. Maybe I can
turn one off for curise which would save current draw. A spare pump
would cost about 1/2. Redundancy, which is always a good thing.
Plumbing might actually be simpler since I have two radiators. The only
downsides I see is weight, space and check valves. I finally found the
WP-136 on Summit. thier PN has an S on the end. It looks like the
current draw is 1/2 of the WP-337 if I'm to believe the mfg.
OK, I've made the decision, it will be two WP-136's.

Hi Bob, somehow these numbers do not pass the "smell test". There is no way
you can pump 20 GPM with the back pressure in the system on 5 Amps alone.
Larry's observations below make sense. A little air blower motor moving air
uses 5 Amps.
