Vacuum Leak

Ok so I replaced my oxygen and coolant temp sensors. Now my car is not idling high enough to stay running when put into gear. I found where my vacuum leak and I replced the hose but it still isn't sealing right. My brother in law says it's the fuel pressure regulator hose. If I push down on it while it's in park it pretty much stops leaking and the car idles lower. When I let off of the hose you can hear the air hissing out of the leak. I have a picture of the hose if anyone would like to see it to give them any ideas. Thanks.

yes put up a pic please

How do I go about posting pics here?
