Here you go guys. Check valves and nipples ready to go. It’s old school racing stuff, no doubt it will pull a vacuum. How much power it makes for our motors and when is questionable, but at the least it’s a great way to get rid of the crankcase fumes.
Run the vapor to a baffled Catch can then thru a vacuum brake booster power valve and out the exhaust.. not sure if its bonneville approved since you will be running in the modified gas group you'll have to check the rules.
