First, thanks to Rob Ridge (Topwater All Day) for supplying me the photo.
Does anyone know the name of this part. It's used the block the pressure port on the Oil Pick Up Assembly on top of the oil reservoir cap.

Without the cap it looks like this. On my Nitro Z19 and several others the hose to push air into the oil reservoir is not connected here, it is connected to the top of oil refill hose, so this port is blocked to maintain pressure inside the reservoir.

Hopefully this is a better pic than the first one.
