1992 Mercury Grand Marquis FUEL LEVEL SENDING UNIT; The gas guage does not function. Where is this sensor located and how do I access it to replace it? I took this car for an inspection sticker, the guy said come back in 2 hours. When I drove away after inspection the gas gauge no longer worked. The guy said he has no idea why. But it was fine before he inspected it

The sensor is located inside the gas tank, you can access the sender from the front of the tank, just make sure the tank is less than 1/2 full or gas will gush out when u remove the sender retainner ring on the tank to remove the sender, u will need the car on a lift to do this...
in all the years I worked on these I replaced maybe 4. so no not a common problem, but the new clean clean burning gas we use does contribute to failure, the chemicals they put in it affect the longevity of the sending units.
why do u keep repeating the post, I have read it, u still must perform the same diagnostics, the relation between the test and the problem changes nothing, what could he have done to affect the guage?, I have grave doubts that they are related. remember we do this on our own time for free,(not employed by fixya, (40 years in the field of auto repair) so take my advice and do the connector test at the fuel tank, if that is ok then replace the sender.
