My daghter just bought a 97 blazer, and the fuel gauge reads wrong. I have replaced the gauges and they still read the same. The guy she bought it from said the fuel pump, I am assuming the sending unit together, and that didn't fix it. Any ideas.

Did you actually replace the sending unit? Is the gauge not working, like its not accurate? Or is it all the way over to the right or left or what? Please explain more in what the guage does.

Thanks and let me know so I can help.

If by wrong you mean that when it is out of gas it still reads that it has gas, and it stays on full a long time, or the oppisite.
The gauge assy. In the tank is usually a long stiff wire that has a float on the end. It has to be adjusted or bent so that when the tank is empty the float is almost on the bottom of the tank, when it is full the float raises the wire that connects to the sending unit in the tank that sends to the gauge in the dash. Also make sure you have a good ground between the gauge and the body. You can check the gauge by removing it from the tank. Leave it connected, and lift the float up, and down to see it it works good and steady by watching the gauge on the dash, of course you will have to have some one watch the gauge while you or who ever is lifting the float up and down.
Hope this helps
Good luck
