Fuel Gauge for the Obsessive
Here's a fuel gauge that is really neat.
It's a CruzPro gauge.
Here's how it works.
1. You completely drain your tank.
2. Then you add a quart, litre, pint whatever unit you wish.
3. You then tell the gauge you added it.
4. Repeat steps 2 & 3 until tank is full.
The gauge then remembers each reading versus the sender in the tanks resistance.
After that it is dead nuts accurate to whatever the unit you have chosen.
It ain't cheap.
I found a used one on line for about half price.
