Here is a link to an article I wrote several years ago about the Yamaha
oil
transfer system. I hope it can help you.

"Carefully remove the unit, making sure the black foam sealing washer
stays with the tubular filter element. If it remains in the tank, the
seal can be forced into the feed hose going to the engine-driven
metering pump which could block the flow of oil."

In taking my sensor out, I didn't see any filter like that. Would
that be something in newer motors?



If you have to, drain the engine tank and look for the sealing washer and
install a new one on your sensor screen. Also make note of the screen
positioning over the sensor assembly so it will not airlock the oil and keep
it from flowing. Yamaha does not have any type of warning system if the oil
is not reaching the pump.
