How to adjust gas gauge to read right not reading way over filled like it does now. When 1997 chev 350 vortec truck gauge is at 1 st red mark close to empty, better not past gas station ! ! !


the fuel level sender is inside the fuel tank, part of the fuel pump assembly. did you or was the tank replaced before??they may have bent the float arm on reassembly . you can buy the sender from your parts supply store .you will have to drop the tank to do this it clips onto the side of the pump assembly. run it almost dry first as the tank is big n very heavy even 1/4 full. you can try to bend the old arm

but its very hard on the "sender" as for level indicator full to empty, think of the shape of the tank narrow at top to widest point in the middle (full to half) wide middle to narrow bottom( half to empty)

its just an overall volume thing

Town and Country Van running out of gas and guage says half a tank what could be the problem?


If your fuel gauge is showing you in accurate readings this is normal to all vehicles that are not used to fill-up gas full regularly but sometimes the cause of the inacuracy is due to faulty float valve in the gas tank you need to replace it

The gasoline floater in your tank signals full or empty to your dash is stuck at that level.

2000 Chevy s10 fuel gauge fluctuates. Sometimes stays at full sometimes stays at empty and sometimes shows correct fuel level.


sounds like a bad connection to the sending unit. or the float is getting stuck or contacts are worn

Dash gas gauge stops showing proper gas level once it hits half a tank. Then gauge will fluctuate between empty (light will come on), full and anywhere in between but seems fine from full tank to half


If the trouble with the gauge started after you worked on it then you likely damaged or created a restriction to the movement of the sending unit. You will have to remove the tank and double-check your work.

Car of year 1998, when tank is full or medium from fuel, guage shows empty. When tank is completely empty, the guage shows full. Guage is of digital type with the bars. What can I do ? Any tests I...


Digital gauge also gets its input for fuel level from a float in the tank. Here the culprit can be that float because the error is systematic i.e., full on empty and empty on full/half. If the reading was erratic then it was something to do with IC in the bars display panel.

My fuel gauge isnt working, it sayed over Full untill i hit half a tank then showed on F then 1/2 a tank was actually Empty. what could be wrong?


The fuel sending unit has a rhetrostat its a variable resitor ..As fuel is added the fuel lever mover along the rhetrostat and gives resitor signal to the fuel guage, the fuel gauge interpets this as level indicators to show on the gas tank.
