Welcome to this forum! I've moved your thread into the stock 91-94 section. You have a couple of metal straps holding the tank in place. Disconnect the fill hose, fuel lines, and the electrical connectors. Place a floor jack with a board under the tank, then lower it. You might not have to drop it completely to get to the sending until. Don't put stress on the fittings. Always make sure that there is no pressure in the fuel lines before you disconnect the fittings.
