Faulty fuel level indicator readings on 5th Generation Chevrolet Corvettes can be electrical and or fuel system related. Tracing the condition to the fuel system could be a sender problem. Bad signals can also be attributed to faulty ground connections and cables. There is also the possibility the instrument cluster has problems requiring and refurbishment.
check your ground wire to the gauge
Try to see if there is a common ground wire to these 2 gauges. If there is make sure it is grounded to a clean dry grounding site and see if this helps.
can byou buy a permanent in-line fuel gauge for a 1992 corvette
needs a fuel level sending unit 100 percent sure
fuel gauge on my 99 buick centry custom stays at full , then drops to empty. Is there a fuse or relay that i can have my neighbor look at it
Looking from the rear of the gauge apply +12v to right terminal and ground to left terminal. If functional the gauge will go to full. Reverse wires and the gauge should go to the left below empty. If it does these two things the gauge is working and the problem is wiring or sending unit. Randy Nix
1984, Corvette the fuel gauge stays at 1/2 full all the time. Plaese help.
Possibly a punctured float in the tank.
Most likely, there is a small hole in the plastic float in your gas tank's sending unit. As the float fills with fuel,it sinks to the bottom of the tank and sends an "empty" signal to the gas gauge. You're gonna need a new fuel pump. Scott
On most vehicles when the fuel light comes on you have about 1.5 to 2 gallons of fuel left in the tank. On a vehicle without a fuel light when the fuel gauge reaches empty it may very well be empty.
with a full tank of gas the gauge will drop to "E" then after a few seconds it will jump back to correct reading.
this is a problem with the gauge cluster. very common problem. you may also notice the neeedles moving very erratic at times. it is a common problem with s10/jimmy/blazers/sonoma
