I'm curious here guys if my coolant pump works by pumping a large mass of coolant rather than a large operating pressure. My hose from the pump to the nozzels fitted on the machine has a 4mm ID, and so I'll pick up a 6mm or slightly larger hose tomorrow and see if the larger diameter will increase the flow as it doesn't appear to be as powerfull as I first thought before I extended the housing.........and hopefully all going well tomorrow I should be able to get a small video of the flood coolant operating during a run.
