    Check the duck bills aren't lose. As they tend to swell and need replacing

    Check the hoses

    Drivesharft seal could be gone.

    If 07 and earlier the pump hose was prone to cracking. That's a engine out job and if it needs a new hose you need to drill a 100mm hole to get to it on the firewall.

    Alternatively you can fill up the hull with water and zip tie the duck bills and don't fill it up higher then the air intake. Check for leaks.
