i was checking my car the other day and i notice that the vaccum hose connecting to the z-tube broke off... so now i am running a stock tube with the JWT pop charger... i was wondering is the vaccum hose very important or not. if i dont connect the hose what will happen in the long run.

is a pcv hose.. is not good to have a vaccum leak.. you gonna have idle problems.. air/fuel mixtures is gonna be unmetered right.. is best you get it replace
