Autolube

[labreeole]

Hi, I have a 90HP outboard , year mid 90's.
It is an autolube model. There seems to be a small leak on the autolube tank -half way down where the cap fits for the oil pump.
Does anyone know the type of fitting under this cap. Is it an O ring.
I dont want to remove it before I know what is underneath.
Your experience will be appreciated
thanks steve
ps I do have a photo of autolube tank if that helps

That is oil level flaot switch and it seals to tank, probably need to replace it if leaking.
