Who is using the AEM FailSafe?
 

Want your opinion on it as far as ease of setting up, use, and doing what it is suppose to do.

I think the main question should be - does it work?

I have been using it for over a year now as just a gauge and it was working pretty good until two days ago. The gauge isn't showing flow now but I now there is flow because I checked the boos switch and the solenoid plus the level is going down on the tank. I am running mechanical per turbo and the gauge was showing about 450cc at 21 psi of boost. I am gonna call my vendor and see if they warranty it.

That's not a good sign. :/ How often do you add water? Size tank? Just curious.

I have an aluminum tank that holds half a gallon. It usually last me about 1/2 to 3/4 of a tank of gas depending on how hard I drive.

From videos that I have seen, yes it works.
Part of my question is: ":doing what it is suppose to do?".
