RB20DET Madalist Fuel gauge Problem

[C33_RB20DET]

Does anyone know how to repair the fuel gauge in the gass tank of the Laurel C33 Madalist?

i have tried to clean the circuit board on mine to get a readin but it does not work for long..when i clean it out it just goes to under E on the insturment panel and then it just sticks on half.....another time i got it to work well and it was on full(F) but ten again when it reached to half or around half it didnt move.....now i saw the gauge on the instrument panel go to E...Half...and Full so i know it work there...so it must be the gauge in the tank...would i would like to know is what i can do to make it work properly because at the moment its on half and i never know how much fuel i have.....

Sounds like a sending unit problem in the tank. Did you install a fuel pump anytime recently?

yes i did change a fuel pump..dont even know what kinda it is i just had to get one cause the one i had before just failed...so it was like a quick fix...dont even know if i'm gettin the right pressure from this pump..have to do a test this week on that.....anyway...the pump i had before that came with the car when i bought it had the same problem just that it was a littler better in that i could have gotten a reading from half to full accurate..but not under half.....now since i changed the pump i dont get anything at all..its just stuck on half.....it moves a little from time to time but nothing much to talk about....

whats a sending problem and how can i fix it? thank you for the help and ideas btw..
