We have an Onan 5500 that will start, but sort of sputters and may stay started, but may also shut down after a couple of minutes or so. We are starting to suspect that there must be a kinked breather hose. The reason why we say that is because we emptied a lot of gas from the tank (we have a toy hauler so we have a pump for the toys...but we don't want it to go bad so emptied it into our jeep)...anyway..and we heard a large metal noise that sounded like the tank pressure adjusting. We opened the gas inlet and you could hear the air movement (ghostly whisper is best comparison, LOL). So...we are suspecting that our generator is having trouble overcoming the pressure. We had to go so we didn't test it but I suppose we could leave the gas cap on the inlet loose, and try running the generator.
Question: Is it possible that there is a breather hose that is kinked? (I did try searching, but hope someone reading this knows the answer, and where it runs if a yes). Thanks in advance for any help!
