Default Fuel guage issue

Hey everyone
let me just start off by saying i have looked up the issue and found a solution but i am just trying to check.

So i was driving my z around after a couple of weeks and i saw that the guage showed it was at a 1/4 tank. I remember hearing that if it goes under a 1/4 tank, the fuel pumps could burn so i took it to a gas station and filled it up until it clicked. At first i was surprised because it clicked when only 9 gallons were put in but it has a 20 gallon tank. When i sat in the car, i saw that the guaged showed 3/4 of the way full.
I somehow got to the point that i needed to just add 1/4 on the guage myself when i look at it but i wanted to find a permanent solution. So i looked around and found that it is a common issue and the best way to fix it was a new fuel sensor but i was hoping for a cheaper solution. I kept reading and found that someone said to fill up the tank between 1/4 and 1/2 and it will fix the issue over time. I dont know if this would work so that is why i am asking. If anyone has a solution that does not involve replacing the sensor, that would be great.

No, there is no reset to fix this that I am aware of.
Mine goes to half a tank and is about 5 gallons down, goes to E and has about 7 gallons left. I've just learned to deal with it

you could try, with extreme caution, taking the fuel basket out of the tank and cleaning the contacts on the fuel level senor. Deal with it or pony-up the cash to replace the sensor/basket.

a "cheaper" fix would be to take both fuel sending units out and clean the sensor with electronics cleaner, but with the amount of labor involved, it's best to just replace the sending units themselves. Owners have reported cleaning the sensors only temporarily fixes the issue and it returns slowly / within a year.

The fuel pump assembly is easily accessible on the 350Z. Just replace the sending unit ($123.00) from Z1. Shouldn't take more than an hour to complete the task.

As OldmanZFL suggests, you will get the most reliable fix by replacing the sending units from both tanks with new components. And as bealljk also mentions, be very careful if doing this yourself. You will have the fuel tank open, and you are working in a very confined space. You could have a significant life changing event happen in a second or two. Whenever I work around sensitive electronics or combustibles, I ground myself with a wrist strap.

when my basket is out I cover the opening with a piece of metal.
