The pump is inside the fuel tank.

You need to disconnect the filler and vent tubes, support the tank with a jack, then unbolt the straps that hold it to the frame and lower it so that you can access connections on top. Then you disconnect the tubes and the electrical plug and pull the tank out. There will be a large round plug where all the tubes and the wires go into the tank. This is held in place by a lock ring, which is usually very rusty. Use penetrant oil. There are special wrenches for this lock ring, but you can use a screwdriver and a hammer, just be careful not to shear off the lock ring tabs. With the ring off you should be able to lift out the whole sender unit and see the fuel pump attached to it.
