Thanks Jonathan for the 8mm dimension, maybe I'm being thick, but is that the inside diameter of the Hose? Also is this a standard size to fit directly onto the pump outlets?

John mentioned, the system will be under pressure, so will I need jubilee clips on the hose at the pump side, or is the hose a very tight push fit?

From a lot CNC builds I've seen, people have a blue liquid in the coolant system. What is this, standard automotive anti freeze?

Thanks
Adil
