I found this article and tried it last night. It works. My 15 gallon tank is now a 20 gallon tank!

Interesting, but I'm not sure I'm fully on board with that concept.
Here's why. Early on, it was easy to determine which tank was which. 15 Gal tanks were always Steel (carried over from later CJ's), while 20 gal tanks were plastic. I have never seen a 20 gal steel YJ tank, or a 15 gal plastic YJ tank.
I owned a 90 YJ and learned the lesson the hard way. The salesman told me I had a 20 gal tank, but it was steel. I bought the jeep new and drove it around for the first time, before ever filling it up, and RAN OUT OF GAS. I went back to the dealer and complained about my poor mileage (thinking it was a 20 gal tank). The service manager told me it was a steel tank, and those were always 15 gals.
So, later on, I go to buy a new 92 YJ (4.0L engine), and the first question I ask is about the tank. This one is plastic. The guys says it's 20 gal, as stated on the window sticker. I make him go back to service and confirm. They tell me the same thing.
I've also owned a 76 CJ and it had a 15 gal steel tank, which I replaced with a 25 gal steel tank.
That's why this article is confusing. I owned a 92 and and it was easy to spot the 15 vs. 20 gal tanks. What did Jeep do that I didn't experience?

I think they went to the single tank starting in 91. The 90 models would have had two different tank models.
All I know is I had around half a tank according to my gas gauge and after removing the tube as stated in the article I was able to add 14 more gallons to the tank. At least that's what the pump said and I've never been able to add that much more in before. 😀

That's interesting. I don't think I've ever seen the 15 gal plastic tank. I'm glad the mod is easy.
Was your tank plastic or steel?

It's a plastic tank. I had only been able to fill it with 15 gallons in the past. I had my suspicions at one time when the gasket for the fuel pump wore out and I was able to get a little more than 15 gallons. I suspect now that it was venting at the worn gasket and was allowing for a little more fuel to be added. After I replaced the gasket it wouldn't fill more than 15 gallons again. After removing the tube I now get a lot more than 15 gallons in there. I'm going to run it down to empty and see how many gallons total I can get in there at my next fill up. 😮
