I have a Mercury Mariner and it has a full
tank but the screen says low fuel. Do you
guys know what does that mean?
If the fuel gauge is reading correctly it is most likely the fuel level monitor is misreading the signal from the fuel tank sender, but it will have to be checked to be sure, if it is you may have some trouble getting the right parts if it was a Mercury only part. A lot of FOMOCO parts were used on Mercury's but there were a few exceptions.
