I am trying to learn about how the oil injection system works. On my brothers boat, he has a remote oil reservoir tank with a hose that goes from it to the motor. There is no squeeze bulb on the line and the hose just sits loose in the tank. I didn't see any wires going to the tank? Now on the motor, there is a small oil reservoir with a float assembly?? coming out of the top with wires. How does the oil get to the motor tank and when? Does it need a squeeze bulb to prime the system? I am sure I will have more questions, so thanks ahead of time. Jim
