Is Anybody's Fuel Guage Wonky Like This?

  1. My gauge goes properly to the bottom line when the tank is empty, but when I fill the tank it only shows 3/4 full. :thinking:
    After I drive a few miles it will slowly creep up maybe another 1/8 tank, but it never reaches the full mark.
    It's really not a bother and I will probably never fix it, but I do wonder sometimes-
    1.) Will it get worse? Is this a sign of impending chronic gauge failure? Should I be doing something to arrest it's potential demise?
    2.) When the gauge says it's empty, do you suppose I might actually still have 1/8 of a tank or so? ::)

    The tank was rusted when I bought it, so I had it removed, cleaned, and coated on the inside so it would never rust again. Might that be related to the problem?
     
  2. Mines been like that since I bought it (4 years)
     
  3. Filled mine up on Thursday and it did exactly that - hit 3/4 even though it was brimming and then rose slightly.

    yep mines the same, filled yesterday and it sort of whent to 3/4 then fullish then danced a merry jig.... all i know is when it's in the red it's got about 10 litres in so i don't worry about the top end as the bottom end is quite accurate.
     
  5. Your sender is broken - take it out and look for breaks in the wire :)
     
  6. Isn't that the thing you have to cut a hole in the floor behind the bed to get to?
     
  7. If you have a type 1 engine then yes - or drop the engine. If you have a type 4 then you can remove the carbs, bulkhead and then you can get to it with a little bit of knuckle scraping!

  9. Mine just waves flamboyantly for a while and then sits on empty :)

    could be the float has a hole in it and is full of petrol
     
  11. Mine's the same, fill her up and she sits at 3/4 full. I suppose its fixable but who cares as long as the empty end is somewhere near accurate.

    ;D ;D
     
  12. Exactly - as long as the empty side is accurate then its not a problem - it can be a simple and cheap fix though if you want a little Sunday project :)
     
  13. Mine has never read above 1/4 full so I rely in the odometer to see how far I have gone and when to fill up. The speedo stopped working today. Illegitimate child. Sorry, I needed to get that out of my system.
     
  14. i never fill up more than 1/2 tank max, reason being, my 1st car mini 1100 special, was nicked i"d just done one years tax and a full tank! boy , that hurt , nick my bus and pay the petrol bill yerself, expect they"d bring it back !!
