Ironically the tanks are the same size, the 15 gal tanks just have a lower breather/check valve tube, causing it to click off sooner...
There is a write up on how to drop the tank and cut the tube shorter and make it a 19 gal. Hows that for Chrysler making a buck on upgrades? Same tank, same skid, same pump, different tube installed on the assembly line, and probably part of a package that cost hundreds more.
if you are filling up and seeing 14+ gallons, you have the 19 gallon. I have driven mine through the warning light, to the needle being lower than the E, to the point of weighting my options on how I am going to get to the gas station, who am I gonna call for help etc...and only been able to get 12.5/13 gal in when finally filling.
I had a YJ and did the 19 gallon mod. But the writeup I used said that TJ are actual different size tanks.
I find that to be a bit contrary to my TJ experiences. My wife's rig has never had fuel put in it without the low fuel light having been on for at least 30 miles. That is unless I happen to have been driving it and then I fill it up as soon as possible after the LF light turns on and that is maybe a total of 5 times.
And yes, she has been warned repeatedly that if she runs out of fuel, call someone else.
Same here. I take the light as more of a suggestion than anything else.

Old thread, but I recently when I had a bunch of time at the gas station decided to see how much I could get in it. 18.9 gallons believe me or not I even kept the receipt, but I could not have put another drop in if I wanted too.
2000 Sahara, 3.5" Rubicon Express Lift, 1" spring spacer & 1" Body Lift, 33" or 35" BFG Mud tires, Front & Rear ARB, Rancho 9000 shocks, UCF Ultra High Belly Up
The below is tank part numbers are the size of GAL= tank no matter what your build sheet says. I have a 99TJ and thought it was a 19 Gal but the part number on tank and cross reference to below chart shows it is a 15.Gal. Now I know why 11.5 gals is the max I can get in tank at fill up.
EP0=All 2.5L Gas Engines
ER0= All 4.0L Gas Engines
