Ok I have been working diligently on my fuel gauge. It only travels to a little over 1/2 full even if the tank is full.

I had to rebuild the gauge and physically ground the sender and the gauge to get that much out of it.

Then I turned my attention to the sender. I removed it to see if it need to be adjusted....not. In the mean time I broke it. So I took it apart and repaired it.

Still no improvement. I have 2 questions.

1. The gauge does move up slightly when I rev the engine. Why is this? I have a new sender and new wiring harness. The gauge moves to extremes if I close or open the circuit. But in the truck it only moves a small amount. I suppose I should be happy it works at all.

2. I was amazed when I took the sender apart that there is an open connection in there. The rheostat (I think that is what it is) is in a small unsealed case. Just a piece of copper moving a long a coil. I am sure gas gets in there. How does it not ignite? I realize this is a very low voltage and there is theoretically no spark under the fluid level and when there is constant contact but what about when the tank is almost empty. This just puzzles me. Any of you engineers or chemists out there care to enlighten me as to how these don't ignite?

If it can be built ... It can be fixed.
