Gas tank skid plate removal.

I need some guidance on removing the skid plate over the gas tank. Is this supporting the tank? How many and where are all of the bolts for the plate located.

I'm trying to install a bumper and I cannot get to 4 of the bolt location because the skid plate is in the way.

Help me out before I start smashing things!

The skid plate is supporting the gas tank. I had to drop mine this week to fix a leak on top of the tank.

The only not-so-obvious factor is the straps. On the rear of the tank, there are two nuts/bolts which are the ends of the straps. Those do not have to be removed. Excluding those, there are three on the front and three or four on the back. Make sure you disconnect your battery and have a floor jack ready to take the weight of the tank as you loosen.

there a couple of good threads out there with more detail

I replaced the gas tank on my 87 YJ many years back. Sand and grit will get between the gas tank and skid plate and eventually rub a hole into the gas tank.

Anyway, the best I can remember is that the skid plate does hold the gas tank in place. It is very easy to remove the skidplate and gas tank and can be done with one person and a floor jack. The less gas in the tank the better when you go to do it.

If you don't need to take the tank completely out, you shouldn't really need to disconnect anything except maybe the filler hoses and vent, which I think are just hose clamps. Then you can remove the front and back bolts and lower the tank using the floor jack. Keep an eye on the fuel lines and the wires going to the top of the tank and you might be able to lower the tank just enough to gain access to what you need to without having to disconnect anything else.

Hope this helps.

removing the tank isn't hard at all. The biggest annoyasnce is the exhaust tend to get in the way. Much easier is you remove the tailpipe, or just have someone pull on it to get it out of the way. I did it by myself but it was a pain; wuldv'e been faster if someone was their to hold the pipe away.

Also helps to have a piece of 2X4 to spread the weight on the top of the jack. Mine had 7 or 8 gals of 3 year old fuel in it and it was a pain. Like said above the less fuel the better.

Take the filler and vent hose loose, take off the 4 back bolts, drop down enough to do what you need or if complete removal is necessary, you ave 3 hoses up top and then 3 bolts up front. lower tank and skid out of the way.

Hardest part I had was the front bolts. Something about cutting wheels sparks and gas in the same area.

I can tell you from experience the nuts holding the plate to frame is some kind of crush type nut. it gets wedged in at factory went they tighten bolt. So later in life it just spins when you crank on it. I ended up welding some nuts on 1/8" steel and sliding it inside frame. Of course I was replacing that section of frame. So I had it completely cut out of jeep. Passenger side drilled small holes and pumped it with no blaster first.
