turbo coolant pump

[Kevin Phillips]

There could be a temperature issue, the chemicals run at around
38c/100f so coolant/engine location might be too hot. Inlet and outlet
sizes start at 1/2 inch and up, depends on flow rate of pump and yes,
attached via standard hose and clamp.
Could be other pumps available as well, anyone look through Granger or
RS components ?
