    Fuel gauge issues

    G'day all,

    I was driving my 76 Game home from work this afternoon and noticed that my fuel gauge was incorrectly reading. It is current reading half full when I brimmed the tank. I had noticed earlier in the week that it seemed to be reading a bit off compared to the normal fuel consumption over the week. My inital thoughts are that it might be a bad earth somewhere or the voltage stabiliser.

    I had trouble with the fuel and temp gauges rising and falling in unison about a year ago and a new voltage stabiliser fixed that up. I hope that hasn't failed so quickly.

    Any further suggestions before the fault finding starts this weekend?

    Sounds like a bad earth.
    Have you tried an IC voltage stabilizer? They apparently work well.
    If all else fails you could adjust the guage.

    Let us know how you get on - I have no reading at all for fuel/temp. I'm going to remove the dash and have a fossick.

    If the temperature gauge is working normally, it is not the voltage stabiliser. If both are playing up, suspect the stabiliser or its connections.

    If it is only the fuel gauge, best guess is a faulty earth on the tank sender.

    So it was the sender...

    So after checking all the wiring, guage, earths and voltage stabiliser, I pulled the sender out to find that it was a home made job... The float must have broken at some stage and a home made float was in its place which had rusted and partially filled with fuel. Floats don't work so well when they are filled with fuel. So I have ordered a new sender which should fix the problem.
