Venting issue/question

Vents PCV Crankcase Valve Cover.pdfVents PCV Crankcase Valve Cover.pdfVents PCV Crankcase Valve Cover.pdfCurrently I have the crankcase vent tube disconnected, the valve cover vent has a small filter, and the PCV valve has a rubber cap secured with a clamp.  After doing some reading on each, I realized that I should make some changes to ensure that gases are not building up under the hood, foreign material not going into the vents (either ccase or vcover) and that i should protect both from backfire pressures if I connect them to the airfilter and/or to the  PCV valve.

It seems that having the PCV valve connected to the Crankcase vent is beneficial beacause it has slight vacuum to help remove vapors (including condensation), pressure reliefing and minimize overall vapors from building up and entereing the cab area.

I am not concerned about re-directing those vapors to the combustion thru the pcv valve but want to make sure that I am not directing any backfire if it happens into the ccase or the vcover compartments.  I did a drawing of possible connections and would like someone with more knowledge than myself to take a look at it and see if it makes sense.

Components needed are: hoses, Anti backfire valve, check valve, and 2-hose T-Connectors.   Any Suggestions/Criticisms?
