Ok I've searched and the gas caps listed to fit a 76 FJ40 appear to be Non-Vented. Has anyone found a cap that truely is stamped "Vented". I've followed a couple part numbers listed here on Mud and nowhere on stant or Napa's website have I seen "vented" called out. They just say it will fit. My PO tossed the charcoal canister and I don't want to hook all that stuff back up. Drilling a hole in my cap would be my last option unless someome had figured out a way to add a motor cycle style check vent.
