Boy, you aren't going to like this much. It's a nasty job. From the service manual:

Fuel Tank Removal

Remove the seat and top compartment.

Remove the fuel tank cap and overflow tray.

Fuel Tank 1
Fuel Tank 1

Remove the right side cover. Remove the rear master cylinder mounting bolts and push rod clevis pin. Do not disconnect any brake hoses or rear suspension air hoses.

Fuel Tank 2

Turn the fuel valve off. Remove the inlet hose from the fuel pump. Turn the fuel valve to RES to drain the fuel tank.

Fuel Tank 3
Fuel Tank 3

Remove the rear wheel and shock absorbers. CAUTION: Be sure to support the swingarm so it does not drop and possibly damage the final drive gear case or brake hose.

Fuel Tank 4
Fuel Tank 4

Disconnect the tail light and turn signal wires. Remove the hand rail and both sections of the rear fender.

Fuel Tank 5
Fuel Tank 5

Remove the left side cover. Remove the battery and the battery box. Remove the left engine mount plate and remove the fuel valve.

Fuel Tank 6

Disconnect the fuel gauge wires. Remove the tank bolt and cross plate.

Move the fuel tank toward the rear of the motorcycle and out of the frame.

To reinstall the fuel tank, reverse the removal procedure.

I know that I am a newbie, but the service manual I have for my 82 doesn't make mention of removing the shocks and tire. Is it possible to get it out without tire removal?

You must not be looking at the Honda service manual then, because that's where those pictures are from.

And the answer is no, you must remove the rear wheel, because the tank comes out the back.

The tank still puts up quite a fight coming out the back even with the wheel off.

you weren't kidding about it being a nasty job. the only difference I could see in the instructions that you showed and what I had to do is remove the rear shock "manifold", it was directly behind the gastank. I neglected to take a pic though, sorry.

Another tip, the arm that holds the rear brake mount needs to pivot to the left. This gives an amazing amount of room so the tank can drop down and out. This room is especially helpful when putting the tank back in. I only wish I had hooked up the carburetor linkages before I put the tank back in!

And one more tip, wait to install the petcock until after you get the beast back in and bolted down.

that is the next thing to do on my bike, (83 gl1100 interstate) it has been sitting for 20 years with the same gas in it. need to get a service manual and take lots of pictures. tires needed to get changed out anyway so two birds at once.

To MJSantos. you are absolutely right. Lowering the rear 2" and pivoting the brake brace was exactly what I needed.

I removed the petcock as well.....

What it looks like once you finish pulling the tank. Pay attention to how the wiring harness which connects to the rear lights (turn signals and brake lights) is routed before removing tank, to be sure you have proper clearance for it when you reinstall. Also pay attention to how the airlines for the rear shocks is routed (above the frame or below the rear fender). A great opportunity to replace old hoses, old clamps, old hardware, clean in hard to reach spots, lubricate, and check rear brakes.
