Low Fuel Light Comes On At Random Times.

[HughMann]

I purchased a MJ on the 4th of this month. It had been sitting since 2011 when the PO passed away until 4/9/13 when it was re-registered by the PO's wife and It had less than 100 miles from the inspection mileage when I bought it.

 

The issue is that the little yellow low fuel light comes on at anywhere from 1/3 tank or less and will go on and off depending on if you are going up or down a hill or around a turn with some speed and sometimes it will just go on and off on flat ground.  I am guessing part of the problem is that it has only had maybe 2 tanks of gas through it since 2011, but is there a fuel level sensor that might need to be cleaned?  I am also guessing that the only options to change said sensor if there is one is to  a) drop the tank or b) take the bed off. Am I correct on that assumption?

there are no baffles in the tank so the fuel will just slosh around.  the cure I have found is to keep it above half a tank at all times

sounds reasonable.

Mine typically does that too. Also, I once dropped my tank (was going to replace it but the replacement Napa sent me was an Xj tank) after the low-fuel light came on, and then could barely lift it back into place with the fuel still in it. So I drained it, and there was still 10 gallons in it...
