Be aware that flow is only half of the equation, you also want to  
know the pressure, as discussed on the other thread.

I think there's an article in the Tech Guide on it.  Roughly, you  
could use a relay to power the pump, and ground the relay through the  
switch.  Adding a separate manual switch would allow you to power the  
pump to prime the engine after an extended sitting.
