[Jamo]

Mine is in the trunk with the filter as Steve points out--has the double pump look. I've got mine set up to run full time...no mechanical. I like the fact that I have to go thru the sequence of the battery switch, the pump and and the fans for turning on the car. A little noisy...but an authentic noise that is quickly drowned out as soon as the motor starts.

Safety-wise...who gives a sh!t? 40 gallons is gonna make such a big-assed fireball that the arruminum grenade will make it all moot. If I ain't dead, I hit the battery switch and it kills the pump and thereby, the motor...a mechanical will run as long as the motor runs.
