Definitely the gauge can be changed, provided the float in the fuel tank is OK, i.e. no leaks. This float connects to a potentiometer which records the current flowing thru it and displays it in the gauge. So before replacing the gauge measure the current and match that against the quantity of fuel in the tank...............sodeep

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.

sounds like you probably need a fuel level sender. it's located in the trunk on the right hand side attached to the fuel pump. I got one on ebay for about 20.00, but you might as well replace the fuel pump while you're at it, as it can go bad with time.

if the gauge starts a 0 - goes to 1/2 , than full - sounds like gauge is OK - seems to me like the sending unit is bad - you could try removing the sender and trying to clean out the port with "brake clean", letting it dry than re-installing it. the pressure switch is still the least expensive place to start
SOURCE: 2002 monte carlo fuel gauge doesnt work,pump works ok.
It is likely the fuel level sending unit. I had a customer with an 03 Monte Carlo that the pump went out and the fuel gauge hadn't worked in about a year. We replaced the fuel pump module and it took care of both problems. I believe the sending unit is available separately from the complete module.
