    Disconnect the clear hose from the back of the MFD. Apply mild water pressure from a garden hose spray nozzle into the disconnected hose end behind the MFD to flush out the hose and the pitot hole under the hull. You should see it peeing out from the pitot fin leading edge onto the ground.

    If the clear hose will not easily flow water then look for a kink or crushed spot in the hose.
