There are two or three connections on the tankcar dome depending on the type of oar,, Where three connections exist, one is a two Inch diameter unloading line which extends to the bottom of the car, the second is a one inch diameter air inlet connection and the third is a two inch diameter pressure safety vent, which is a thin lead disc adjusted to release any pressure in excess of 60 pounds gauge,, This safety vent is hooded for protection against dust, dirt or accidental bumping.

However, I guess some lead salts do get into the crankcase oil and if it is extensively used for fattening hogs in farming communities I wonder what might be the result.
