”tank ventilation-MFI diagrams“
I think we concluded from the above thread that the ’69 and RoW systems may be simpler and this was only for USA and a few other.
At the rear of the air filter assembly there are three hoses; the oil/water drain from the bottom that goes to the “dribbler” at the engine oil cooler, the crankcase breather from the oil tank and the return from the charcoal canister in the fuel evaporative emissions system.
Best,
