Who is using some type of automatic fuel pump shut off in case of a crash? I've heard of oil pressure switch and impact sensor. For the oil pressure switch to work, the engine has to die, that might not always happen soon enuff. An impact type could potentially cry wolf on a hard launch in the final round after you've clawed you way thru a 132 car field.

So who uses what, how is it working out?

Thanks,
Joel
