Hi guys, my dad says that since I plan on putting so much into my celi, (interior and exterior red glow, seats reupohlstered in red/black leather, reverse glow gausges, etc...just bragging

...) that I should get a fuel cut-off switch hidden in the car to turn off when I leave so the car only has enough fuel to get a few blocks if stolen unless the switch is turned back on. (It closes the fuel line from the tank and leaves the engine with only what it already has) I was just curious as to any methods you guys think would work. I told him the security system I'm leaning toward has starter kill. What is starter kill and is it effective? My dad says that a fuel cut-off is the best bet and I just want to know more about it and how much it would cost and just some general info. Also I would just appreciate any ideas that anyone might have (bucket of water hanging over driver door, giant rolling boulder, boxing glove on a spring, ejector seat, etc.) lol but I seriosly do need ideas. Help me out!!!
P.S.- Sorry for this LONG ASS post!
