[Spridgets] Water pump

[derf]

I've never really run a hi-rev A-series.  But, I know Ron S has.
I would tend to listen to what Ron says when it comes to racing Sprites.
If electric pumps were good for racing Sprites, he would know.
No, he didn't pay me to say good things about him.  I just hate to see
people try to re-invent the wheel when we have experienced wheel
engineers giving good advice all day long.
