help with gas tank

Trying to replace my leaky tank...
Got exhaust, driveshaft, lines everything off, but I can't drop the tank itself. The two rear bolts are hopelessly rusted, even rounded (evil, evil salt). As you may know, there isn't much space to work with...any ideas?

Vise grips above the rear subframe

Or hammer on a socket, extension with flex joint might fit

Ratcheting wrench helps on the back bolt

If none of that works, you may have to drop the subframe

Damn, I was hoping it wouldn't come to dropping the subframe...thanks for the advice, I'll try that.

Make sure to use an impact gun if you have one. I dropped my tank last week and if I had used a ratchet on my rusted bolts I would have stripped them for sure because with the impact gun I was sitting there hammering each bolt for about a 30 seconds before they'd even move.

None available, but how the hell did you manage to fit an impact gun anywhere near there? I can barely fit a socket extension...

I'm guessing you have a hoist.

I happened to have my subframe out at the time, it does make the job much easier ...assuming you've had your subframe off recently and it's not seized to the body of the car lol

I wish I had a hoist...

We're talking about a $400 beater here...so it's all jammed up. I guess I'll try sawing it off, and fab up another attachment point. I got a nut splitter, but I'm not sure if it's a nut or bolt head on the bottom (I had two bolts and one nut on the fronts, the rears are too cooroded to tell.

In other news, I am jealous of your ground clearance (nice pic too!)

Victory on the bolts...
Now, the tank is loose (everything disconnected), but I can't get it to drop. It seems that there isn't space betwen the crossmember and th footwell to get it out!

Again, any ideas?

Yup. Got under it and wiggled, no go. Then I tried judiciously applying some hammer, and it fell right out. Awesome!


Now, gotta put everything back and replace the shocks.

I'd check the brake like junction while everything is out. that short line is VERY common for rotting out. It's easiest to replace if you have the subframe slightly dropped. also rust coat the area under the tank. lots of moisture gets trapped up there. main reason for the tank rot to begin with. also sent you a pm. you gave me the wrong number..lol

New tank is in and connected! Now to replace the driveshaft and exhaust...but not too tight, as I'll have to take it all out again to replace the CSB in two weeks.
