Help I need to drop my gas tank

My advice is to use a floor jack with a piece of plywood about 12"x12" to hold up the tank. Then unbolt the tank and skidplate from the frame. This way you can slowly lower the tank a little and have some room to disconnect the filler neck as well as the supply/return lines. Also, the wires from the fuel guage sender need to be unhooked. This next tidbit is common sense and I hope you don't get insulted, but I have seen guys try it. Do this with an empty tank. I had a customer bring in a YJ with a caved in (he smashed it on a rock) tank to be replaced, the tank was as full as it could be. In it's condition it only held maybe 8-9 gallons but it was still a pain in the butt. Also remember that an "empty" tank is full of fumes and can explode violently so be careful. No smoking and if you have a gas furnace or water heater in the garage where you are doing this shut them off, even the pilot light. I could tell a couple stories about an uncle of mine and my H.S. wrestling coach but I don't want to turn this post into a novel. To keep it short, never braze an "empty" gas tank and remember that part about the water heater.

If you are doing this to your yj and have a 20 gallon tank you are going to be in for a lot of fun. The problem is that when everything is unbolted, the gas tank still wont come out. The filler neck that comes off the drives side does not easily clear the frame on its way down. Trying to angle the tank by bringing the passenger side down first will not work as it contacts the exhaust pipe. I was able to get mine down by using a large crow bar and forcing the filler neck past the frame. It is a little scary, but the plastic (assuming your is plastic like mine) seems to give just enough flex to make this possible. Once you start you will figure it out. I have seen people have to remove even the spring so your case my be different. Good luck anyway.

...I had to drop a gas tank out of a mazda once and it was pretty easy. Never did a Jeep though...only advice I have which is hopefully common sense also would be to mark the fuel lines so you know where and what they are, maybe draw a diagram...whatever...just so you know when it's going back in...It makes it easier going back in...How's this for forgetful: when I did the tank on the mazda...got it back in hooked up the lines started bolting the straps back on...and then it dawned on me...Did you connect the filler hose!?!..Doh!!...had to take it out again...*heh*...On cleaning the tank...I had mine boiled at a shop (it costs about $50 bucks)...and then I cleaned it at home after that with muratic acid...That's what they were going to do and I figured I'd save myself a little money..the muratic is cheap and you can get it from any swimming pool supply store...NOTE!!...You cannot use it on all tanks...it damages some metals and will eat through plastic...It was an option for me because my tank was steel...
Good luck on it...*wonders how he would do this on the '60 willys since the tank doesn't come out...at least it doesn't look like it*

Ok, I have the experience in this area. I replaced the sending unit in my 87 YJ Tank.
Remove the gas filler cap
Remove the bolts holding the filler neck to the body
Remove the skidplate (have a small jack underneath) by unbolting it at the rear
and then under the body.
The tank should drop when you have the bolts undone and then you can disconnect the wiring and other hoses that are attached. Its really not hard, just breaking the bolts off of the hold down straps is a pain in the ass!

Hope it helps
