Yuck! I was thinking of lowering the transaxle or cutting the body above the tank and glassing it back would be much easier for as I am much better at bodywork than mechanics.the hatch isn't in the way, I did remove the strut on the left side but the tank pins itself between the body and the engine.
You should be able to get the tank to hit the cam towers, then you either remove engine parts, lower the motor, or raise the body off the chassis. or a combo of all three.
If you haven't gotten the tank past the side bulkhead and up against the cams then you are not coming out of the hole correctly.
The tank only comes out of the hole one way, it is very tight and it is easy to get stuck on the way out or in.
The way to pull it after you remove all the brackets and the seat belt and the throttle is to work the outer edge up and back a tiny bit first. Keep going that way till you are able to clear the drain pipe. It will pretty much be up against the quarter window. Keep rotating the outer edge up and in till the top of the tank is facing the opening and the engine. If it doesn't want to go this way you are not getting the front outer corner up and rearward enough.
This is the only way the tank comes out. I am always amazed how tight it is, and how it has to be just right or it gets stuck.
