Question Low Fuel Circuit Suggestions

Please help. I am trying to put together a low fuel warning lamp circuit using a radio shack "led" with transitors and resitors ect.
What I would like to do is use the 0-90 ohm sending unit side of the autometer fuel gauge to signal the led to light up at about 20-25 ohms or
1/8" of a tank.
I tried a circuit I found here at Team Camaro posted by SOA Nova but I could not get it to work with the "led"
I know I can buy something at Classic Industries but what fun is that
Any suggestions would be great.

Re: Low Fuel Circuit Suggestions

Did you get it to work with the 12V radio shack light ?.

Re: Low Fuel Circuit Suggestions

You need a window comparitor circuit. You can make one with a comparitor IC, or an op-amp and a hand full of resistors. RS should have all the parts you need. I estimate it will cost about $5 to build.
