    I have the same problem on my 99 ZR2 Blazer. This is the the rheostat in the gas tank. I bought my part in Ebay for $27. The only issue is that you have to drop the gas tank and pull the sending unit to install. Hope this helps, I hear from other message boards that it is a very common problem in these vehicles.

My gas tank is full but the gauge say,s that its empty and then full, and then half full what is wrong with it


You need to replace the fuel gauge sending unit. This is mounted on the side of the fuel pump assembly, inside the fuel tank. You will need to remove the fuel tank for this repair.

99 cavalier - the fuel gauge doesnt read accurately and it jumps


Possibly a bad ground wire at the sender on the tank,

Check for that first before tearing into the dash to replace the guage.

It is more likely to be the fuel guage sender which is faulty.

99 chevy silverado fuel gage malfunctions


A bad electric connector is possible. A bad tank sending unit can cause the same symptom. Usually the sending unit is a reostat mounted inside the tank.. it changes resistance depending on the float position, the resistance change causes a different voltage to the gauge or signal processor. The reostat may be a resistive plastic strip, as the float moves a contact pointer wipes the length of strip thus the change in resistance and voltage. Clear as mud?

Gas gauge in 99 chev blazer


sorry, but there is no real economical way. the only way is to change the fuel pump and they sell 2 different kinds of units, one that is 2 parts and the whole thing and it runs from $200 to $380. since the fuel pump still works i would just meter my mpg till the fuel pump goes out.
