If you have air being sucked in then you could usually identify where by covering each joint with shaving cream and looking for a disturbance when the pump is activated.
I am still concerned by such an apparent big difference between the pressures at the feed and the vent. As they are less than 150 mm apart they should be at virtually the same prressure!
They dont appear to be at the same pressure!
