I think that the problem mainly lies in the Fuel Sending Unit. Check that its Fuel Level Sensor is all right and is the latest model. I am telling this because if it is not the new one, it can cause corrosion in the sensor and cause shaking and fluctuation of the Gas and Fuel Gauge. I think you can get it.
Thank you Sir, have a nice day.

How to drop fuel tank on 1988 surburban


Drain the gas tank. I didn't have a lift so I used a floor jack under neath the gas tank. I used a piece of plywood on top of floor jack that would fit between tank straps. Take the fill tube loose, take fuel lines and electrical connectors loose. Take tank straps loose,you may have to drop tank a little to reach some connections. If I remember correctly the fuel pump is in the middle of tank. I don't know if you would want to cut hole in floor of surburban to reach pump? I don't have any info about cutting that hole, if you try that, that is your responsibility.

At 1/4 tank the needle starts to fluctuates. is this nomal?


fuel tank holds about 12-14 gallons and with the fuel low in the tank it sloshes around and moves the fuel level sender causing the fuel gage to fluctuate. there is a shield in the tank that surrounds the sending unit to stop this but sometimes they come loose and move or don`t work as effectively. how many miles to a tank depends on different factors. mainly on how you drive. in general you might get around 18-20 mpg.

Gas Gauge fluctuates, Overheating even with enough antifreeze & Heater blowing freezing cold air.


GAS GAGE IS EITHER A BAD SENDING UNIT OR "SLOSH MODULE" IF A FORD. HEAT ISSUE IS A VACUUM LOCK IN THE COOLING SYSTEM AND NOT ALLOWING THE AIR TO ESCAPE AND NO WATER TO CIRCULATE.CHECK FOR LEAKS ,THE THERMOSTAT,AND WATER PUMP FOR PROPER CIRCULATION

1999 Chevy Cavalier fuel gauge doesn't regulate the amount of gas properly. What causes this?


Hello
This problem is caused by a defective fuel gage sending unit, the sending unit is located inside the fuel tank and is part of the fuel pump module but is sold separately in a kit from ACDelco, to replace the fuel gage sending unit requires the fuel tank be removed from the car. Below is a price and part number courtesy of rockauto.com

1999 chevy cavalier fuel gage


Most of the time the level sensor in side of the fuel tank is the problem. I'd say 1 out of 10 the cluster is bad. But with the way you say it was acting up before hand I'd put my money on the level sensor and not the cluster. The fuel tank will need to come out of the car to fix this. There is not access door to the fuel pump.

Gas gauge malfunction and engine light stays on


This is a common problem with Malibu's. It is due to cheap metal in the fuel gage that corrodes. Chevrolet knows about this but they refuse to issue a fix. The check engine light staying on and the faulty fuel gage are related. This is a defect and they need to recall this part! Raise hell with the dealership!
