1997 SL780 Oil Starvation

Help please. I had the same "run then die" as a previous thread here. After the 3rd trip to the lake, I noticed that I wasn't using any oil. Tank still full. Hoping that I hadn't scorched cylinders, I checked and seems ok. Hot warning light never came on. Disconnected the tree oil feed lines to carbs and ran again to test. NO OIL FLOW. I have flow in the oil supply line from the tank to past the filter. Because of the carb bank, I can't see the device that splits the flow into three carb feeds.

Is this device run by vacuum? Is there a simple reason that I'm not getting flow to the carbs? Anyboby?

The oil pump has three outlets and it's run off a gear which runs off the crank. If you are SURE you get no flow replace the pump or go pre-mix??

I checked my pump by disconnecting the oil lines to the carbs and cranking the engine.It does seep out the tubes but very slowly. I would imagine at higher RPMs that it flows much faster.
