Oh yea those meziere are great :) Almost 20 amps draw at 12 volts or 240 watts or
one third of a Horse Power. If you are lucky they will ALMOST  pump as much as
10% of what a Mazda water pump will pump :) Real stupid of the Mazda engineers to put
in all that pump capacity when they did not need it :)

Now if you believe all that I have a bridge in Minneapolis I'll sell you.
