hey everyone,
I saw in a previous thread some of you talking about how to make your gas tank go from 13 or 14 gallons to around 19 gallons. I think something about a filler, just wandering if anyone can give me details on how to do this?
Thanks again.

Here ya go Bud, hope this helps......

Cool thanks for the link I will try it tomorrow.

In case anyone has any doubts about this, I can tell you that it actually does work. I tried it yesterday and this morning went to the gas station, I already had a little over a quarter of a tank, and still put over 15 gallons. So that with a quarter of a tank should be about 20 gallons.

That's good news. I was thinking about trying that soon.

Is it just my yj, or do you guys have trouble leaving the automatic run on the gas pump nozzle? I don't know if its cause the neck is small on the tube to the tank or the angle or what, but I have to hold the handle on the nozzle for every ounce of gas I get. Anyone know what I'm talking about?

Yeah I have to do the same thing with mine. I can sometimes turn the nozzle sideways and make it work, but by the time my tank is full it is to late, and gas is all over the ground. So no real good solution for it as far as I know. Just figured it was one of the luxuries of having the JEEP. If anyone has a good solution I am sure there are a lot of people that would be greatful!!!

just a tip, when removing the vent tube I found it easier to get a screw or bolt that is just big enough to thread into the tube, and pull the tube out that way. rather than trying to fight it with a pair of pliers. this will save you a lot of time and pain.

That is actually a great tip. I had a very difficult time getting that thing out with pliers.

Im having trouble with my fuel gauge on my 89. Im pretty sure the gauge is fine, but im not sure if the ballon in the tank is broke or what. i really dont know how any of it works, looking for some pointers and education. thanks

i took off my license plate bracket and just took one screw and put it in the upper left corner of the plate and it gives me a better angle to shove those damn gas nozzles in there. that way i can get back in and outta the cold weather.

I removed the tube from my fuel tank vent yesterday. Was able to pump 18.9 gallons into that 15 gallon tank. Hmmmm...Interesting!

I shortened the tube in my YJ gas tank today... 15 gallons into a tank that read between 1/4 and 1/2 full.

WoooooHoooooo....

i've got a question about doin this? does your gas gauge read past full now, or does it just read full for a longer period of time and the start dropping down once the gas reaches the original level on the tank? or does it say empty before it is really empty? i'm just wondering bc i dont wanna accidentally run out of gas or think i'm almost out when i'm not

Mine will read a little past full and stay there for a longer period of time. Once it reaches where full used to be it will start working properly. So you dont have anything to worry about. When it says empty it is empty.

yeh... same problem with the whole auto feed at the gas pump. I figure it's just more quality time that I get to gaze at my jeep instead of the dollar signs ticking away. I can get it to work sometimes by pulling the nozzle out an inch or so, but then it wants to fall out so I still have to hold it. I let my license plate kick up and hold it and sometimes... maybe... it works... good luck

sometimes the ballons get saturated with fuel over time and stop working, or read less gas then actually in the tank. then can break, it is a "working or moving" device. a lot of year, and a lot of gas, not real hard to replace...

why cant i just keep pumping gas into it? Do i hafta do the mod to the tank or can i just keep filling the tank to 20 gallons?

Only if you want to wear 5 gallons of gas down your pants legs.

i guess i figured if my 15 gallon will hold 20 gallons y not just keep pumpin? Are you kiddin? 5 gallons of gas is like 20 dollars...lol

i have a 91 wrangler i have put in 4 fuel pumps in the last 5 months it seems after i get gas the pump stops working it just cuts out or i can't get it started again. any suggestions

[QUOTE=torylv]
This is the right thread. Go back and look at the beginning of this one.

i found on 88 yj that the oil pressure sender was bad and causing my gas gauge to do strange things. the fuel gauge and the oil pressure use the same power and ground in the dash. try to unplug your oil pressure sender and see if your gas gauge reacts normal.

No worries, I believe mine came stock from the factory with the 20 gallon, and it does the exact same thing.

i tried this trick today. it is not as easy as you guys say it is. i got it done though. i will get gas this weekend and see if it really works. thanks...

I got the same problem at the gas station but I really belive that this has something to do with the vent tube.
The vent tube is responsieble for shutting off the gas pump.
If you leave it out than it will mess with you everytime you gas up your car.
WHY, If you inser the gas pump into your car and turn on the pump, than the flowing gas will run into your tank (OF COURSE hahah).
Now because there is no vent tube sticking into the tank, the gas will enter the tank right next to vent hole BUT the vent hole is no longer protected from the vent hose, so the gas can splash into the vent hole and causes you gas pump to shut off.

But this is my opinion.
So the question is did you take the vent tube out or did you just cut it off.
If you cut it off and still got the problem then I am wrong.

Here's how to fix the gas-pump problem. I do not recommend it to anyone.

The automatic shutoff is triggered by back pressure, as sensed via a small hole or holes on the outside of the pump nozzle, near the tip.

A person so inclined could find a short piece of plastic or rubber hose, the diameter to just slip over the pump nozzle, and the other end small enough to fit in the tank fill opening. (The pump end may need to be flared or stretched to do this.)

To pump, slip the hose over the nozzle, but without blocking the back pressure sensing hole(s). They must be open to the outside air. Put the other end in the tank and one can fill at full speed. This is probably illegal, dangerous, and foolish, and I wouldn't do it if I were you. But it works for me.

SAFETY WARNING - the pump will NOT shut off automatically! You must be ready to release the trigger as soon as the tank is full and before it over flows!!

Don't try this at home, and if you blow yourself and the gas station up, you didn't hear about this from me.

What's the smallest tank used on a YJ?
My gas gauge hasn't worked since I got the Jeep so I just guess when to go down and fill it up, I've guessed wrong a couple times and run out but it only takes about 8 gallons to fill up.
I guess I need to pull the tank, fix the guage and figure out why so little to fill it.

Prolly have a big dent in it like my XJ... I only have 3/4 capacity, at least thats what the gauge says when the gas stations pump stops.
