Hey i have posted on here before but i never got a response so im gonna try again. Well my problem has to do with my fuel guage and its components. I get a normal reading on it till about 3/4 of a tank, then it plummets to empty and never comes back. I was curious if it is my fuel sender unit that has gone bad or if its something else. I have taken the whole assembly out of my tank and i checked the gas level float and it didnt seem to have any holes or cracks. So any help regarding this issue would be greatly appreciated.

Thanks in advance

i forgot to include the make of the car: it is a 1990 convertible

 

If I could help, I would. Never had any problems like that Sorry.

 

This has been covered before, next time you may wish to use the search function found in the upper right-hand corner of this page.

But to answer your question, the float in the fuel tank is either misaligned, or has a hole in it and no longer floats correctly.

Also remember that the float is normally bottom weighted on the RX-7 (meaning that it is not linear), and it is normal to have the first 1/2 a tank be used up, much faster than the 2nd half.

 

Icemark mine is backwards to what u said. The second half of my tank goes faster?
