Part #52 is the oil pump:When my Poulan P3314 type 1 is sitting not running the bar oil leaks out all over.
Some Poulan saws us a plastic tube that is push fitted into the case just behind the metal bar backing plate. the other end is wedged up into the corner of the oil tank beside the fill cap. By setting the saw with the left side down, you are actually submerging the end of that vent tube in the oil, and create a direct passage for the oil to flow out of.Part #52 is the oil pump:
Besides the above, you can either replace the pump, fresh rubber, everything seats tight against each other, etc, OR try setting the machine on it's left side, so the pump is the highest and the oil tank is low(gravity isn't help the oil escape).
This is the tank vent, There should be a cloudy colored tube that runs to the upper left corner of the oil tank from that spot. The connection spot on the tank that you show is below the oil level in the tank. At about the middle level point.Attached photo is where oil is leaking out from

I have two Stihl and one Echo chainsaws and none of them leak chain oil like this Poulan. The Poulan also has a lot of compression when pulling the starter. It is fairly new...2016. I bought it used . So far it has been nothing but trouble.
