A 3A pump wouldn't be able to do much better.
There are some 20gpm pumps out there that draw about 5 or 6 amps and move 20gpm which is fine for one bank of 4 lightly worked cylinders.
Like this one:
20 GPM - Water Pumps, Electrical - Cooling & Heating - SummitRacing.com
(it draws 5 amps)
1 to 3 amps could work for cold start and low load driving on a small engine.

The pump I have now uses 7 amps, the low speed setting I made goes through a big "battery charge limiter" and slows it down drawing 5.5 amps.
I plan to up grade to a 55gpm 10amp pump put together 4 and 7 amp low speed settings and put together a 16volt emergency power battery pack for short bursts of high loads in very high ambiant temperatures.

The alt delete and electric coolant pump dont really go together so well.
