Oil pickup tube 251

[Jeffs]

Can anybody tell me if there's supposed to be an O ring between the pick up screen and the pick up tube on a 251?

Not a 251, but my 218 & 230 did not.   That swivel joint is immersed in oil.  And must be free to float up/down.  An o ring would not allow that

Thank you so much for confirming that, I didn't see one in the manual but before I button this thing up I wanted to make sure!
