Question type: Maintenance & Repair

I'm having trouble filling the gas tank. It
takes 1gal and  then fills up the neck. Then
the pump automatically shuts off. I know its
almost empty. Thinking its like an evap

1 Answer


The gas tank vent is plugged or kinked. If it has a evap can then it is likely plugged up.
