Yamaha Oil Injection System

[macojoe]

This is a response I got from IBoats

hello
what is happening is when the oil transfer occurs the engine tank cant vent or the float does not shut off the oil transfer. the resulting pressure in the engine tank can push the float assy out of the tank. if you remove the float assy and the filter screen and drain the oil tank you will find a rubber seal between the filter screen and the tank. the seal should be replaced or at least retrived everytine the filter assy is removed. the filter assy has a hole at the top that must line up over the flat on the float assy. if it does not the transfer may not shut off proerly.
good luck and keep posting

My book does not mention this seal?? were does it go, I belive that it goeas on the nipple on the bottom of the filter screen?

When I put the filter screen back in I move it till it falls into a hole, is this right?? Then I put the float in making sure the arrows are alined.

I am sure I am doing something so small but it is making a big problem.
