SOURCE: fuel gauge problem

The nature of the gauge is that it should behave with a linear taper between full and empty. If it works when full but then malfunctions as the level drops, the variable resistor in the sending unit which is housed along with the fuel pump in the gas tank is almost certainly at fault. The sending unit will have to be replaced to fix the problem. Expect this to be an expensive endeavor.

SOURCE: Gas Gauge not reading correctly

The most likely culprit is the sending unit in the tank. They are relatively easy to change, as long as you don't have much fuel in the tank. It's a mechanical unit that has a float that raises and lowers with the fuel level, however with age, the floats can develop leaks and no longer float, of the electronic portion of the unit can go bad and not register the proper level. They are replaced and an entire unit, so it doesn't matter which happened, you will need to change the fuel tank sending unit.

SOURCE: 2002 honda crv fuel gauge moves really slow.

I had the same problem. My battery was going bad. When I replaced it with a new one, the fuel gauge worked fine.

HI, the fuel gauge sending unit is malfunctioning. this is located inside the fuel tank and, it is part of the fuel pump assembly. replacing this failing component will fix this issue.

SOURCE: 2002 Chevy Suburban: Fuel gauge reads empty, tank is half full

Youre gauge is controlled by a plunger in the fuel tank which is attached to the sensor and the fuel gauge. it sounds like when the plunger goes down half way its either getting stuck down lower then it should. Needs replacing. Any mechanic can do this install for you.

The gas gauge on my 2001 Nissan Altima shows full when filled up, but only tets to 1/2 full when it is near empty. Suggestions?


Either the fuel tank sender in the tank is bad and needs replacement, or the fuel gauge is faulty. I would bet the one in the tank is probably bad, because that's usually the case. Find the connection at the fuel tank, disconnect it and use a VOM to get a resistance reading while the tank is empty and reading 1/2. It should match the specs.

Fuel gauge doesn't work


mine did the same thing 2 years ago. i assume it is probably the fuel gauge sending unit in the fuel tank so i priced a new one. as i remember it was about 350.00 for just the part. my computer reads in gallons and is still accurate as to telling me how much fuel i have used so when i use 10 to 12 gallons out of the tank i fill it again. so far i have had no problem doing it like that. just don't run out of fuel because that is really bad for fuel pumps. mine has a 14 gallon tank so i make sure that i never go below 12 gallons used. i usually try to fill at 10 gallons used

When gas tank is 1/4 full and I fill it up it doesn't show I have a full tank until I drive 15 miles.


Normal. There is a resister in the fuel level circuit that slows down fuel level readings. A gauge that responded instantly to a sloshing fuel level every time you went over a bump or around a turn would drive you crazy.

I have a 1998 Corvette with 42k miles. Recently the fuel gage will drop to empty after filling the tank and driving for about a half hour??.. Is the a Fuel gage Fuel Pump, Fuel filter Problem?...


I had the same problem with my 98 Corvette with 69K miles. Mine did exactly as you described soon after I purchased it in November of this year. I went online and read posts of others with the same problem and how to try and fix it. At 1/4 tank add 2 bottles of Chevron Techron cleaner and fill up with good name brand premium fuel. The Techron cleaner will clean the sulfur residue and other contaminants off of the fuel level senors in each of the left and right hand side gas tanks (C-5's have two gas tanks on either side connected by a transfer pump with each side having it's own fuel level sensor). I did this and so far after nearly 3 tankfuls there's been no recurrence of the problem. However, if this doesn't help then the alternative is to replace some if not all of the components mentioned earlier. I got a $1300+ repair quote from my favorite garage prior to applying the above fix. I'm no mechanic and I may have some of the actual part names incorrect. I hope this helps you out and fixes your problem! BTW, you can also use a full can of SeaFoam cleaner in lieu of the Chevron Techron cleaner. I used the two bottles of Chevron Techron the first tankful and used SeaFoam in the second tankful. I plan to use a bottle of SeaFoam every 3-5K miles to help keep this problem at bay and keep my fuel system cleaner!

1996 Plymouth Grand Voyager Fuel Gage issue


It sounds like the fuel level sending unit located on the fuel pump is malfunctioning. The solution for this is to have it replaced. You can do this yourself but I wouldn't recommend it as the vehicle needs to be lifted and the fuel tank needs to be dropped out. This can be preformed for about 100-150 in most shops.

1993 sentra jerking problems.


I wanted to just give a suggestion...do you go to the same gas station to get gas? My sentra ran horrible because I kept going to this same gas station. My gas would get low and it would start cutting off and trying to cut off. I let my fuel go to almost empty and then went to another gas station to fill up. It hasnt cut of for about 6 months now and I havent returned to that gas station.
