Question about 2001 Chevrolet Silverado 1500
Could be the float in the tank. It may have sunk to bottom and lifting up when disturbed by a bump or something. If you can get to sending unit the connections may be loose or dirty.

Youre gauge is controlled by a plunger in the fuel tank which is attached to the sensor and the fuel gauge. it sounds like when the plunger goes down half way its either getting stuck down lower then it should. Needs replacing. Any mechanic can do this install for you.

when you changed the fuel pump, did you bump the sending unit in tank. or a wire to tank may be the problem. maybe sending unit in tank is bad!

Fairly common problem with GM vehicles. The sending unit in your tank has a small circuit board that an arm is attached to which moves up and down according to your fuel level. This circuit board and arm are not making good contact. Unfortunately the only good solution is to replace this part.
