I installed my alcohol injection kit yesterday drove it around everything was all good. Tonite i drove it again system was injecting. Then i got off the boost and the spray light stayed on. I know it was spraying bc I was getting knock retard at low boost. The system sprays when you use the test button at idle. Could the boost hose have come off and caused this problem? Any information will help.
Spray light is on, but no spray

No, if you blew off a boost/vacuum line the alky would stop immediately.
Is this an SMC kit? If so I would contact Steve at SMC, no one knows the kits better.
How long did it stay on after you let off the gas? Was this kit recently installed, or has it been on there for a while

I just installed an SMC kit yesterday afternoon. Followed the directions to the letter (it was really easy).
Went for a test drive, and the kit appeared to be working like it was supposed to.
The spray light would come on right at 10psi boost. Did a little tuning and thought I had it adjusted pretty good. Came home and washed the car, with a big 
So then I go out after 10:30 looking for a Mustang or F-bod to play with. First time I get on it, all of a sudden the knock gauge shoots all the way over to the red
. Looked at the alky control box, and the spray light never came on. 
I hit the prime button to test it. The light came on and the engine bogged, so that worked. Then I eased on the throttle and built boost slowly, all the way past 12psi. The spray light never came on.
I parked and started looking over every connection. Didn't find anything wrong, so I back off the wastegate to my previous non-alky setting. Decided to hang it up for the night and go home.
On the way home I give it one more try and viola, the spray light comes on right at 10psi. Let off the gas, and the light stayed on. I tried turning both dials, hitting the prime button, and even turning it off, but could not get the light to go off (well yes it went off when I turned off the switch, but it came back on when I turned the switch on).
Any ideas what I should check? Am I doing something wrong?

My Problem Fixed!
I found that the pressure guage at the X fitting was leaking. Alcohol would run down the fitting and saturate the spray light pressure switch. This would cause a short so the light would stay on.
I removed the guage, cleaned the threads, wrapped it with a few layers of teflon tape and re-installed it. It's been working ok since.
