Get the floor mat moved out of the way in the front left corner of the cab. There's an access hole cover there that just pops up with screwdriver. Clean the area well. Remote the small nut that has the signal wire on it. Now remove the screws that hold the sender in the tank. One of them has the ground wire on it. The sender can now be taken out the top. You have to gently bend the float rod a little bit for it to come out. Assemble in reverse order. The float rod will need to be bent some on a new sender and then straightened back once you get it into the tank hole. The sender screw holes and gasket are offset enough so that it will only line up one way.

Thanks Lynn. My tractor has no cab and no floor trap door to access. Its just a steel floor and it appears i have to remove it to get to the fuel tank top
