Okay, a new development: I now have a working fuel gauge. It's not accurate, I'll get to that in a bit, but it's working.

This may not sound like much, but getting to this point has taken:

4 years
Hundreds of dollars
Hours of frustration
And a mechanic who flat out lied to me.

The sending unit in my fuel tank was bad. About a month ago I tried to have the fuel pump assembly replaced. The mechanic told me that my sending unit was fine and the issue was with my gauge.

So I spent 2 weeks gauge hunting before finally pulling the cable off the fuel pump, locating the wires for the gauge, and using a potentiometer as the sending unit. The gauge responded perfectly.

Today I got conformation that I was lied to, and ripped off when I saw the old fuel pump. The traces on the sending unit were blackened. This is the same sending unit the last mechanic told me he personally looked at and tested.


Sooo now onto my current issue:

The gauge gives an accurate reading when I'm sitting still. When I accellerate, the needle goes up, then plummets to empty when I hit the brakes. I'm wondering what the problem is now.
