You need to bleed the air out to the highest point of the engine.
 
If you look at the back of the engine there is a pipe that comes from the end plate and goes to the throttlebody.
 
Remove that and put a pipe on the throttle body side and lift them up, run up the engine until water starts to flow nicely out of the top of the pipe without air.
 
Keep squeezing the silicon pipes to ensure water is being pumped through.
