Now now!  Let's not have any banishing around here. :)

I don't know what the numbers mean but I will let you know how it works
out.  Todd reported his pump measured 4.3 amps at 9.3 gpm (if I
understood his last post).  Mezarie may be reporting the "no load"
pumping capacity, or Summit may have the current wrong.  I should have
the pumps sometime next week.

Any idea what a ball park figure for the pressure drop across the engine
and an evap core would be?  I could simulate it on the bench.
