Brian, I was told that you hook up to the t-stat housing and you do NOT run the engine. Just turn on the water and it like backflushes the motor/drive (currently I don't have t-stats in the engines now ). I guess I would only miss out on flushing the manifolds/risers that way...If you feed water directly to your thermostat housing, your SWP is going to run dry and destroy the impeller in seconds
Phazar, that setup is nice!
US1 & Sydwayz, when you hook up your setup, doesn't the water run out of the drive until you start it, then the water pump picks up the flow? But you have to run it, right?
