Removing Gas Tanks
I'm taking out the fuel tanks so I can weld in a roll cage. I've got the tanks loose by removing the skid plates and I've drained the tanks and removed the 5 lines that go to the tanks where the pickups are. Now they seem to be connected, tank to tank, at the top by a 2" hose. There appears to be hose clamps that attach them to the tanks.
It looks hellish to get the hose off. Any tips?

It is hellish, especially with the trans in place. Even withthe trans out, it is hard to get any grip on the hose to pull them apart.
I cut the hose to get them out after much 'discussion'

I'll be cutting out some of the sheetmetal that makes up the bulkhead behind the seats to make access to weld in the cage. Perhaps that could expose access to the hose?

Not really, the hose (and clamps) are tucked up in the "C" channel section at the top of that bulkhead. One possible method might be fashioning a hook (or looping a cable) around the hose from below. Loosen/remove both clamps, then pull on the loop to get the hose to pop off the tank ends. I think that might work - I'm sure others have some proven method as well.

If you say "I have small hands" ten times. Your hand will be the same size but it should make you laugh before it hurts. It's a pain in the xxx to get the tanks out. But should be done.

The tanks must have been installed at some stage of the cars build because it looks about impossible. Lucky for me I actually enjoy working on the car. I'll let you know how it goes.

Take some pics if you can and post them and any lessons learned for the rest of us please. I watched a TV show on what happened to the Hindenburg last night, don't repeat it with your car, safety first!

The factory procedure I believe is with the trans out of the car. That's how I got mine out. There is just very little room to work with the trans in place, coming up from below.

I just did that job three months ago, and believe me, it is a nightmare. Getting the tanks out is easy, but you need to be strong enough physically to wrestle with them for several hours (in my case) and strong enough mentally to try new things over and over, until you figure it out when going back in with the tanks.
If I ever do that job again, it will be with the transmission and driveline out of the way. I wouldn't wish that on anyone.
Hint, I think a 7mm socket will fit the worm gear screw that clamps the 2 3/4" transfer hose to both of the tanks.
Good luck, and my condolences.

you can get it loose with the trans in the car. I use a 8mm socket on the clamp and then gently pry the hose back off the tank. You also need to remove the left inner wheel housing and remove the fuel fill line. After you have the tank loose and start to let it down there is an evap line on the top you will need to remove also
Hope this helps,

Not only is there the 3" hose, there are also some vent/EVAC lines up there. You need to be carful, as these are very brittle, and contain a valve that prevents splling it you roll your car upside down.
As suggested above, I cut an access panel above the crossover lines, and put an aluminum close-out panel in to cover it.

I got the tanks out faster than it took to drain some of the gas in them out.
The 3" hose clamps were easy to get at and the hose slipped off with a firm tug.
I'm putting in a 4 pt cage welded to the frame. Now the problem is that there is some kind of a fuel vapor tank on the right side were the right side of the main hoop will go.
I'm thinking of remounting it in the wheel well, say just above the brake vent (Z06).
It will take hose extensions and it will sit at a different angle than it did before. Any problems with that?
