An interesting link to Gomog and a bit of a coincidence that, even though you are driving normally on the road, you are beginning to experience the same symptoms as the race cars.
Whilst a bit of a bodge, you could slip the hose off and wrap some insulating tape around the metal part of the pipe, to take up the slack, which will stop the hose bulging.
