those are cool, what does it say about running the pump out of the water
If you run water thru the pump, there is NO PROBLEM running it out of water.
I read much on this; many say never do it, BUT, flytime told me he checked with Berkeley directly, then I emailed Berkeley and got a quick reply that it is NO PROBLEM if running water in the pump.
In fact, the Berkeley guy said run a hose up the nozzle; but it's better to disconnect the inside hose and run it directly into the pump (connecting another hose to run thru the engine to cool).
I used flytime's idea: put a hose splitter on the hose; one hose from splitter has male connector, the other has female; connect to interior hoses; turn pump water on before turning engine; turn engine water on after engine starts.
