I have a JD 5310 55HP tractor with a plastic fuel tank. When I run the tractor hard, it pulls a vacuum on the tank, causing the top to sag down. I have changed the fuel filter by the engine and drained about one quart of fuel from the bottom of the tank (it was clear). This started within the last six months. What is causing this? Is there some other filter I need to be looking at? Someone told me there was another filter around the fuel tank, but I cannot find it or any reference to another filter in my maintenance manual. Anyone have any ideas?

| Yes I agree, it is obviously a tank venting issue,not a filtering issue. As the fuel is leaving the tank air is not been allowed in causing a vacuum which is why the fuel tank is sagging down We had the same thing happen to us many years ago on a MF 168. The engine would begin to falter as if there was a filter blockage, as soon as you loosened the filler cap the air would rush in and the engine would pick up again. replacing the fuel cap solved the problem instantly.

| Some had a external vent that was in behind the smv sign. Others had a vented fuel cap. Which ever one you have is not venting. Good luck.
