Seadoo 3d Di 2007 How does the top end get lubrication?

Quick question! How does the top end get lubrication from the oiltank?
All hoses i can see going from the fueltank is quite far down on the engine.
I imagined that there would be a line going to the fuelrail on the fuel injection or something?

Quick question! Where do the two hoses on top of the oiltank go on a 2007 3D DI?
Thanks!

One is a vent line in the other one is a vent that goes to the bottom of the compressor

Great! Thanks!

It's a 2-stroke, so on the DI the air and oil (as opposed to air/oil/fuel on a normal 2-stroke) go into the bottom of the crankcase with the crankshaft first creating a mist of oil and air then as the piston travels down it displaces the oil/air mix that now travels through the exposed transfer ports and up into the combustion chamber to be mixed and burned with the direct injected fuel.
