Gasoline Line Shut Off

To stop car- jackers from having the car for long, this electric cut off was added into fuel line to shut off flow of gas to carburetor and stops engine when fuel in carburetor bowl burns out.

Circuit is from car battery to coil around tall tower to make electromagnet to lift steel ball up inside the tower area and does this for normal operation when you are driving your car.  Steel ball is not shown.

A hidden switch in drivers compartment, either hand or foot operated can be turned off when in dangerous conditions,  gas station environments, persons running to your car perhaps with drawn guns, ect.  Tuned off the steel ball drops to restrict gas to fuel system.  

Newer cars would need electric fuel shut offs to meet the design of fuel systems of particular car.

Electric solenoid action lifts steel ball when current flows. Open switch turns off electro magnetic and steel ball drops to block off fuel line.

Why?the relay of the fuel pump in the gap and all

My grandpa used the positive of the ignition coil and ran that to car ground. The driver is electrical isolated, however anybody who touches earth and frame pisses all over themselves.

Sheinnail, this is not relay of fuel pump. This is to block gasoline from reaching fuel pump on engine and let hijacker be able to drive away from you before engine suddenly goes out of gasoline.

rich11292000, did car have two ignition coils with secondary to car frame? How does 12 volt positive terminal produce high voltage. I have heard of cars having high voltage on frame driving through rioting crowd.

The spark plug coils produce 15000 volts. grandpa had something that put out more than that. Im not sure if he had a second coil, i would have done it to my car but its to easy to get a law suit these days. I dont understand how somebody can hurt themselves breaking in to your house and they become the innocent, but yet you have a right to put holes in them up until they injure themselves.

To rich11292000, Mantrap Laws make electrified auto frame illegal in many U.S. states. Internet gave idea of electric fence charger from farm supply connected to frame with spark plug wires with chain dragging on ground insulated from car frame for negative circuit. AND IF CIRCUIT IS ON MAKE SURE YOU DO NOT STEP OUT OF CAR. Wild animal situations might warrant shock to keep beast away from vehicle.

High voltage anything is a really bad idea for a car's ICs unless it's over really short distance (as in the ignition system). I'm still unsure why one would make a design so complicated. It's much easier to just use an fully electrical solution: An opening relay somewhere in the ignition system or on the ECU where 12V operating voltage is supplied. I.e., preventing the coils from charging in the first place by severing that connection.

I wore a 12v relay in series with the starter wore from the key so it won't even turn over. Hidden switch under drivers seat. The old coils Rich talks about were easily wired that way. Many old gas stations used them on doors, cash registers, tire racks to prevent theft and raccoons or other rodents out. They could produce upwards of 35kv if on old flathead motors or tractors. Its too hard now with injection systems unless you can find correct wiring harness.
