    Hi All,

    Does anyone here have any experience with their fuel gauge always reading full? (I wish it really was always full lol). Sometimes, it will read correctly which leads me to it being the float. If you have any other ideas let me know! Thanks and Happy New Year!

    I had a Ford that did that and it was a ground wire for the float that was loose .

    Have you had the fuel pump replaced anytime recently? Or has this been an ongoing issue for a long time? I'd believe the float is stuck in the up position.

    Fuel sending unit issue...could be loose connections, chewed on wires from oesrs ir just a faulty unit itself...use as much fuel as you can and drop the tank to "check" or replace the fuel sending unit...7 have one available (non flex fuel) if you need...just swapped out to a DW340 fuel pump and swapped the fuel sending unit as a just in case I need my oem...which I do not...
