oiler issues

[Hiersedgewater]

I have two yamaha 150's. The port engine oiler runs like a champ. The starboard oiler doesn't appear to pump to main tank on side of engine. The alarm goes off the small tank on the side of the engine is at the low mark. I can fill it to the top mark while in the water and the alarms quit and it runs fine till the oil is used up. While trouble shooting I turn both keys on and hit the switch on the back of the engines. I don't see or hear anything from either oiler. I have changed the inline filter on the problem oiler hoping I would get lucky. No change. Before I change the pump out on the tank in the bilge, is there anything else I need to check to confirm this is the problem.

do some searching on this forum about precision blend.the engine tank we call the engine tank.
the remote tank in the hull we call the remote tank.
need a model number for much more information.
