Default Gas tank capacity

What is everyone getting gallon-wise in their gas tank? My 89 looks to hold about 12-13 gallons. I have a 4.0 with auto tranny and the MPG seem to SUCK with my 33's on...

I know with some earlier year YJs you could pull out a portion of the overflow bottle neck an get an instant 3-6 gallons MORE in the tank, anyone know if this is the same for XJs?

Never knew about this that's awesome. Wish I could do it on my 99 though.

Just did this mod about two weeks ago and can now squeeze in about 23.5 gallons. All for about $6 in parts.
