Gas Gauge issue

When I purchased my Jeep the PO said that when the gas gauge got down to 1/2 tank that it was empty. He said that while he had it in the shop that the tank was replaced and it was doing this before the new tank and after. Being one that never leaves stuff along and not wanting to keep up with mileage I dropped the tank and removed the sending unit to investigate. It is a 20 gallon tank and when I looked down in it the through that the float sits in is distorted and there is no way that the float will go all the way down in it. The sending unit works perfectly. My question is can anything be done with the tank. Cosmetically the tank looks great other than the through inside. I am sure the guy I got it from got took, can't imagine that it could have deformed in such a short time. Thanks for any feedback.

The sides on the plastic bowl in the tank are known to warp and the float stops on it and the guage stops in 1/4, 1/2 tank... Do some searching around there are many different ways to fix the issue. I found removal of the bowl worked best for me..YMMV.

I think this is where I am kind of heading with this, does your gauge bounce around a lot without it in there? does it break out pretty easy?

It's not to prevent the gage from bouncing, but to keep the fuel pickup in the fuel when going off camber or up and down a steep incline. They seem to warp now a days due to the friggin ethanol crap fuels. DREDnot had a great wright up on fixing it correctly. Read up on it before you yank it out.

Mine gets stuck on 1/4 and the PO said you better be looking for a gas station when it gets down to there. I pushed it a little on Sunday and when I filled up it used 17 gallons so I guess that was getting a little too close.

Thanks for the tip, I did get in touch with DREDnot and looked over his modification. Seems it's not as critical to have in there with a Carb. motor. I am going to get the gas out of it and see what I am going to do. he was a lot of help as well. This is turning into a great place for Jeep Knowledge.

Remember Knowledge is wealth!! The less you have to spend to repair a Jeep (because someone else has figured a better way of doing it), the more money you have to go and play with your Jeep. Lol

I am running a carb and no return line back to gas tank...with no return line to keep the bowl full figured it was kinda useless...yes my guage swings but no more than anyone elses...I did however adjust my float so when I hit the E I still have about 5 gallons left..also did the 20 gallon mod so I figure I am about back where I started.lol..hopefully that will be enough to keep it from running dry on a incline...I aldo run non ethanol gas so I usually refill at 1/4 tank so I don't get stuck somewhere and have to use E85. Couple good pulls it will come right out...it's glued in a few spots to bottom of the tank.

Well I pumped the gas out and reached in to see how easy it would be to straighten out and the trough made the decision for me. I just barley moved the thing and it popped right out so it's just a matter of putting back together. This is a 20 gallon tank so it should get me there and back and it will be nice to know exactly how much gas is in there.
