We replaced the PCV valve a couple of months ago. This past week the hose going from the back of the carb to the PCV valve blew out last week.

Could the need to replace the PCV valve and the hose blowing out be a symptom of something else?

Is it a proper hose rated for vacuum? It needs to be a hose style that won't collapse under vacuum.
