In the old days they just stuck a vent hose out the top of the tank. Now they run that hose to the engine compartment and burn the fumes under the proper conditions.

The John Deere 1130SE gas tank is vented through a vented fuel cap, which allows air to enter the tank as fuel is consumed. This venting prevents a vacuum from forming inside the tank, ensuring a steady flow of fuel to the engine. Proper venting is essential for optimal engine performance and to avoid fuel flow issues. Always ensure the vent is clear and functioning to maintain efficiency.
It is a 15 gal. Gas tank on them cars I have one.
No
could it be pressure on tank due to unvented gas cap? try running with vented cap.
Possible, but not likely. They are all vented. If it's metal, maybe it was rust, or vandalism, or you bottomed out on something.
A vented gas cap vents the gas fumes into the atmosphere. A non-vented cap system routes the fumes thru the engine to be burned.
