Dead fuel gauge on a 2009 FX50s with 135k on the clock

My first time posting a question on this forum. My question is how often do owners have a problem with their fuel gauge going dead and what is the most common cause.

Is it the gauge itself or are we talking about the actual fuel pump sending unit? Any imput of how I should approach this would be greatly appreciated.

hey this used to happen to me a few times a year. I would remove the rear seat, remove the passenger side fuel pump cover, unbolt the fuel pump/sending unit and just wiggle it up and down as much as I could without unplugging cables or fuel hoses, then bolt it button it back up and it would be good. I assumed the float was getting jammed in the down position. At one point I thought it was related to parking at a slope when the car was at about half a tank, but I am not sure if I could say this was the case 100% of the time

2012 fx50 fuel gauge stuck on empty

lots of issues lately... after the fx was in the shop all day getting the door handle worked on it had 1/4 tank. as I was driving I watched the fuel gauge slowly dip down to the peg, showing completely bone dry. I stopped on my way home, put in 20L but still nothing on the gauge. Later that...

In researching this I did find the two new springss from a TSB that replace the single one on the fuel pump.

Unfortunately for some reason I cannot find those springs again and their part numbers, can you please direct me to them.

Thanking you in advance.
