12 volt gas gauge??

You will do best to buy or build a voltage regulator to drop the 12 volts to 6 volts.

These ae not simply dropping resistors; they use solid state voltage regulators.

You can buy a variable voltage regulator from Radio shack that includes a simple schematic

for hooking it up. This will give a regulated 6 volts to assure that you do not burn out anything such as the sensor in the tank or the gauge on the dash.

Good luck.

The LM7806 will work for you. It supplies a fixed output of 6 volts (the 06 in the part number).

There should be a little hookup diagram in the box or in the Radio Shack transistor manual.

On my Buick 40-56s I just put a seroes resitor to the gauge. I don't remember, but I think it was 64 Ohm. The gauge circuit is a kind of brige system which is not so sensitive to voltage change. It works fine on my car.
