Everything I’m reading says that the 2005 TJ’s have a 19 gallon gas tank, and I’ve been calculating my mpg on this last tank (my first fill-up since getting it).... I waited until my gas light came on and filled up today and it only filled up 14.2 gallons. It was definitely full because the tank actually overflowed before cutting off. Any ideas why it would only be 14.2 gallons instead of the 19 that is the standard tank size for my model? That makes me think it’s a 15 gallon tank, but everything I can find says 19 gallons.
