Where is the fuel level transmitter on a 1994 xjs v12 ?

Usually means the sending unit in the gas tank has failed.

next to the tank at the top of the body under neath. or on the updated version engine bay follow the fuel line and it goes into a contaner with 2 pipes on it that is the filter.

remove covers in boot behind seat there are mounting brackest there hopfully not rusted take off bolts remove brackets remove filler pipe but getting it out is a carry on as its a tight fit may need to remove back seat as well

I wish I could give you an instant fix, but I can't. Do you have spark? If so then its either your fuel pump or the CPS, crank position sensor. If no spark then it could be your coil.

If you tank has gas and your guage doesn't read the gas, then the sending unit is bad or relay or fuse for sending unit is bad.

The problem is with the sensor inside the gas tank since the method of indication used is by passing an electric current & the resistance to that current is a measure of level of liquid in the tank , i.e. the gauge consists of two parts:

• The sensing unit
• The indicator

The sensing unit usually uses a float connected to a potentiometer. As the tank empties, the float drops and slides a moving contact along the resistor, increasing its resistance. In addition, when the resistance is at a certain point, it will also turn on a "low fuel" light on some vehicles.
However if this float gets stuck to the bottom of the tank or a leak fills up the float making it sink to the bottom of the tank, thus always indicating 'E' for empty.........................sodeep

Drain the tank as much as you can and put the gas into a 5 gallon bucket or a gas can, then you need to drop the gas tank down, after you do that you can take out the screws from the pump and it will out.

hello, it sounds like it has something to do with your fuel sending unit located inside your gas tank,on the sending unit it has a float arm that reads the fuel level, some times that float arm gets jammed and wont show your actual fuel level,to fix this with your gas tank at least half full use a rubber mallet or any other object that wont damage the tank and with your key in the start position with the car not running but reading your gages hit the gas tank not to hard but hard enough to lodge the float arm loose, if this is unsuccessful then it will probably be a bad fuel sender location sensor located on the actual fuel sender if that's the case you'll need a new fuel sender. good luck and please send me a update or any questions let me know.

I had the exact same problem. It ended up being the float inside the tank. The float was around $90 but 2-3 weeks later I ended up replacing the whole fuel unit which came with a new float attached. I should have just replaced the whole unit when I replaced the float. If you still have the original fuel unit, you might want to consider just replacing the whole unit. I hope you find this helpfull.
