It is much easier to remove the fuel tank if you remove the filler neck and charcoal filter box first. This allows you to remove the tank with the hood on the car with no clearance problems. You have to take off the filler neck to remove the wires to the fuel gauge anyway. I took mine in and out many times recently as I was reassembling the car. I took the tank to a radiator shop and had them flush it out. Be sure and remove hard fuel lines at bottom of tank first, one has a wire mesh sock as a filter attached. Make sure when they are reattached to orient in towards car. I attached the hoses to the firewall first and then after lowering tank attached the hoses to the hard lines out of the tank. While a PITA, it works and allows a relatively short hose connection. I have heard people say they connected the hoses with the tank not installed, kinda perched on the firewall between the front trunk, but this leaves a 2 foot long hose that you have to wind up and try to tuck out of the way. I did not like this approach. To tighten clamps from below, I got a 1/4 socket with a screw driver tip and this worked very well with a 1/4 drive. The access hole and dimensions are very tight. Good Luck.
