I dont understand. If you put a T line between the pump and the engine, wont the pump be trying to pump the water out of the pump through the hole you are trying to run it into, to wet the pump. How can the pump take water in through the hole it is trying to pump water out. Is the gate valve the water line shut off (like in my water foucite) in-between the engine and the pump. New to the bord and lerning so much.
