I just bought a 96 Chevy Z71 truck. The fuel gauge wasn't working so I had a new fuel pump and sending unit put in but it still doesn't work. If it is the gauge, can it be fixed without sending the whole cluster in for repair? Or does anyone have any other suggestions?

. Use a test light or multimeter to check all under-dash and under-hood fuses:

. With the ignition switch OFF, disconnect the connector going to the fuel gauge sending unit. Measure resistance between terminals by moving the float to empty, half full, and full.

. If everything above checks out, focus on connections/power going to the fuel gauge and the fuel gauge itself.

Hope this helps somewhat.

Thanks for responding. Did you mean the connections on top of the fuel tank from the sending unit? Am I looking for continuity or certain ohms of resistance? Just to add to the original problem description, when I first drove the truck and looked at the gauge it showed between 1/4 and 1/2. The next day it showed empty, so I put in some gas and it didn't move. I checked with the guy I bought it from and he said he was told it needed a sending unit. As I said, I had a new pump/sending unit put in and it showed about 1/4. I wasn't sure how much gas was actually there so I drove it a couple of days and it still showed 1/4. I then filled it up and it didn't move the hand. After sitting overnight, the gauge read 1/2. Assuming the unit is good, it's looking like a wiring problem or faulty gauge. If it is the gauge, can it be repaired without sending off the entire cluster?

Yes. You'll be taking ohm measurements at empty, half-full, and full. I really suspect you have a bad gauge. I'm not familiar enough with your truck to know if you can replace just a bad gauge. On some Chevy products I've seen, you had to replace the whole cluster of gauges. You couldn't just replace an isolated bad gauge.

remove the cluster and clear plastic cover to see if the needle is stuck.. just move it to half with ur hand and put back together

check to see if the leveling sensor is pulled in or the sensor is bad i worked for chevy and have had to replace many leveling sensor in the same vechile cause gm had to update there sensors
