I have a 95 Jimmy 4x4 4 door and fuel gauge bounces all over the place when comes off full. The fuel pump and sending unit were replaced and still have the same problem. I looked under and behind glove box for the fuel buffer that everyone talks about and can't find anything. Any other places where it might be or could it be built into or part of the cluster? I have another cluster that I can try but rather not waste my time if it's not the problem. The only thing I found velcrod under the glove box was the door lock relay and theres about 5-6 purple wires under there in the wiring loom.
