2010 F150 Lariat Supercrew. So, my fuel level gauge quit working a few months ago and I was driving by the trip meter. The gauge sweeps when starting like it should so I figured it was the float assembly. Changed it out and it read pretty close to where it should, but it went only to 3/4 when I filled it up. Is there something I need to reset?
yes, give it 100 miles to match up... Don't know if it "resets" or if there is cosmoline on the brush contacts of the float switch... but I have had the same problem after new level install.
Also ran into a problem I have never seen. No matter how I turned it, the fuel tank module would not come out through the hole in the tank. It was just a little to big to come out. Could the plastic "basket" swell up? If I ever have to replace the fuel pump, I don't know what I will do. It wasn't too bad changing the fuel level/float assembly since I could get the module out enough to unsnap the old and snap in the new one.
If you buy a new float / sensor / or pump unit, it probably came from China... It floated over here on the boat and was exposed to possible weather conditions. They "may" put a thin coating of protectant on the level sensor winding, or maybe it is slightly corroded from setting... that's why I say it might take some time to wear it off, or the gas/ alcohol wash it off.... or maybe it just takes an hour of running to "reset"... I don't know, but I have had two trucks that would read 1/2 tank when the tank was full.. Over an hour of running, the gauge slowly climbed to the full mark. A gauge in the tank, with gas fumes, or constantly under the level should not get corroded.
