I have ran into a issue with my 2003 OX66 225. Long story short I was out Sunday and my low oil buzzer and light came on and went into limp mode so I thought It was just low on oil. So today went out with tank full and same thing happened as soon as I took off. I pulled the cover and tried to pump the tank on the moter mannually and I could hear the pump but it would not fill the tank. What is the chance the lift pump on the big tank could be bad?
