Safety fuel inertia shut off switch.

Almost all cars from like 93 up have them. 90% of the obdII cars at least. what i would be woried about is it dosnt take a hole lot to trip the impact type sensors. if you are raceing it would suck if your fuel shut off after a hard launch lol. but thats just me hook a a low oil ppres switch and a toggle and youll be good :)
