Is there such a thing?
Mine is empty when the gauge reads 1/4 tank. Don't ask how I discovered (IMG:style_emoticons/default/bananabang.gif) |

Not really.
The light in the gauge should go on when there is only a gallon or two left in the tank. Hopefully that still works? If so, rely on it over the needle in the gauge. The sender just varies resistance from full to empty. I forget which way is which; it might be that higher resistance is a lower reading on the gauge? The only way I can think of to calibrate it would be to add a resistor in series with the sender, or in parallel with it. If the light isn't working, you should probably pull the sender out and check it over; possibly clean it up so the float moves smoothly. --DD |

My light does still work so that's good but I want a reliable reading so I guess I'll get a new sender :-( |
