The more cruises and car shows i go to, the more i see people running electric fuel pumps without an ENERTIA switch to shut the pump off in the event of a crash. My fuel pump will pump 340liters per hour at well over 70psi , if i'm involved in an accident i want the pump to shut off BEFORE IT EMPTIES MY FUEL CELL all over me and the wrecked car! They are cheap and easy to install (get them out of any EFI Ford vehicle at an autowrecker) I have a dragracing clip of a car rolling over against the guardrail, squished down so both doors won't open, the fuelpump just keeps on spraying racing gas all over the car.....it bursts into flames and the guy BURNS to death because the fuel just kept spraying out of a -12 hose with a 1000lph pump. Take the time and do it right....the life you save could be your own!
P.S. My car has had one since i converted it to EFI.....it also make a great antitheft device, just smack the button, it pops the contacts open and you have no power to the pump. When you get in, reach over (mine is in the passenger side foot well behind the kick panel) and depress the button down to get power to the pump again.
Sorry for the rant, but i feel strongly about this safety issue. Jeff
