Supercharger cooling Xkr pump need input on diagnosis
 

So I have a customer in with a 2007 XKR. I found a bunch of vacuum leaks which fixed fuel trim problems, everything seems to be running good. one thing that is very different from my car is when I squeeze the hose that goes into the supercharger there is almost No movement of water when it squeezed, comparing this to my car if i squeeze the same hose there's definitely water pressure.
Can you guys with an 07-09 xkr check this for me and see how much pressure you have with the stock pump on that hose? Would help to know if his pump is failing or has failed . Thanks

Air in system? Mine is not rigid, but there is pressure.

If you squeeze it harder can you feel the water moving through or just pressure in the hose?

You fill the fluid. While running, escape the air.

Did you open the cooler filler plug on the supercharger, squeeze the tube and refill?

Yes did all that, hose is pressurized after the car runs but I don't feel the water running through much like on my car , but that maybe because if my uprated Bosch 10 pump
