Default RE: 12v --> 1.2v
Here is what I got so far.
I haven't implemented the volatge reg yet, its on my
todo list.
oh, and Vin will be 12v not 9v
Quite a simple circuit.
LED, BUZZER, and FUEL PUMP CUT-OFF happen only when the tank is being filled
and the float switch is activated (ie, the tank is full [i may replace that with a moisture sensor])

The Pump will never turn off, if you are emtpying the tank.

Comments Welcomed.
