Fuel Gauge Fluctuation.
 

Here recently my fuel gauge has been going from half full to empty to 3/4 tank to empty. Then it will sit on empty for like 2 or three minutes fluctuate again then level out. Any idea what could cause this?

mine does the same thing but its right after i fill it it will say empty then full every once in a while for about the first 1/8 tank then it works fine then when it gets down to 1/8 from being empty it will do it again. :scare2:. its been doing it for a year now i just dont have the money to fix it. i think its the fuel pump and sending unit in the tank. either that or its the great gauges that are in the dash.

my cousins truck did that and when he replaced the fuel pump it started working the way it should again

ya thats what i was thinking about trying first but those things are not cheap they are like 450 so i have just been dealing with it for now. but it seems like its getting worse the longer i wait.

yeah 350 near me... gonna have to cut someones arm and leg off for one.

his didnt cost that much because his is a gaser

MINE DID THE SAME THING OUT A FUEL SENDING UNIT IN IT AND FIX IT, IT WAS 450 AND THEY DONT EVEN HAVE A PUMP IN THEM
