Every time I pump fuel my KIA Sportage spits gas back out at me.

Is your check engine light on? This symptom could be caused by a clogged fuel tank vent system which should trigger a check engine light and related code. If the check engine light is on or has been on, you may want to have the vehicle checked for codes to see if there are any for the evaporative system.

I had the same problem, although there are many solutions, mine was replacing the charcoal filter.
