Excuse me while I break my heart

I believe I have finaly sorted out the stalling problem with the car... There are two hoses coming out the top of the pcv valve one is a vacuum hose that I believe goes to a pcrv (pressure conscious reducing valve) for the purpose of recuirculating crankcase gasses. It seems that when hot the hose collapses at the pcv valve, shutting of the vacuum and choking out the motor. I hope replacing this hose should fix the problem.
