Its really easy. Put a jack under the gas tank, undo the straps that hold the tank to the frame, disconnect fuel pump harness (located near the bumper), lower the tank enough to pull the lines off (watch out for spraying fuel), lower the tank the rest of the way and use a BRASS PUNCH to undo the lock ring on the sending unit. Also take the gas cap off before you pull the fuel lines to releive pressure. Its not hard. If you post where you are from there is probably someone in your area that can help you.
