I bought a 2001 Santa Fe yesterday.It`s the 4 cyl 2 WD auto model.My gas gauge showed 1/4 tank so I filled up.After about 7 gallons the pump stopped.I double checked to see if the tank was full and it was.The question is- unless the gauge is not working correctly,how can the car only take 7 gallons when 3/4 empty? I know that the Santa Fe has a 17.2 gallon tank...PS,the gauge didn`t go all the way to F when I filled up.It was close but not fully on F...
