Rocjeeper Technicly the vent tube is what makes the difference. It's the tube that lets the vapors escape from the tank when you fill it. When you have the tank down and the pump out, reach in through the pump opening and feel for the vent tube where it enters the tank. To let you actually fill the tank to full you need to shorten this tube to as close to the tank wall as you can without crushing the tube because it is imoprtant. I would recomend SHARP one handed tree pruneing clippers, they should fit through the opening and cut the tube easily if they are SHARP, take a file to the blade if you have to. At this point you could use eather pump setup, for the 15 gal tank it will read over full for a while (so what) but empty will still be correct, if you use the 19 gal tank pump it should be accurate for the full swing of the needle.

In theory.

P.S. the filter on the pump should be good for the lifetime of the pump, Ive never changed mine and don't really intend to.

JeepCrawler98 The other difference is the fuel level sender - one reads full at 19 gallons, the other at 15

The pump should plop right in with no problems. If you think about it - the pump wouldn't limit how much fuel fits in the tank anyways; it HAS to suck in fuel from near the bottom of the tank, be it a 1, 50, 30001231209381209381290831 gallon tank. Doesn't matter - it'll suck it in until it can't get any fuel anymore.

amerijeep The difference in the tank is basically how far the filler neck extends into the tank. The farther in it goes, the less fuel you can get in there. There really is no 14 0r 19 gallon tanks at all. Only different length filler necks.

1BLKJP Yeah, all of the tanks are the same. There is just something different in the fuel filler neck that cuts off a portion of the tank for use. There is a mod one can do to expand the users of the 15 gallon tank to 19. I know some on this site have done it and they might speak up also.

As far as how much is left when you are at E it should be 3 gallons. Is your TJ the 6 or 4 cylinder. Because all of the 6 cylinders are 19 gallons.

Gas Tank

I was thinking that it's time to replace my fuel filter, but it's attached to the fuel pump. I saw a fuel pump on eBay that said it was for a 19 gallon gas tank. My build sheet said I have a 19 gallon gas tank on mine, but when the gas light comes on and I fill up, I can only put about 14 or so in it. My first question is: does anybody know how many gallons of gas you have left when the gas light comes on?

Also in the auction the guy said that the 14 and 19 gallon gas tanks are the same size, just the fuel pump is different. Does anybody know if this is true or not? Because if it is true, I want to get the fuel pump for the 19 gallon, so I can use more fuel.

I already contacted Daimler-Chrysler about the matter and they said they didn't know and that I'd have to check with a local dealer, but I trust that you guys know more than the dealer would.
