You need a Good Check Valve to hold the proper Vacuum. I had a Vacuum Issue and removed my Check Valve and sprayed it out with WD-40 and put it back on and it worked fine after that. And, yes my check valve was not hollow.

The Check Valve is slightly expensive. I do not see why one from a Junk Yard would not work if you take a look and see if the parts are inside and still good.
