Yes I mean water injection nozzle when I said injector. The sense line I am referring to is the line that connects to a boost source and then connects to the water injection control module. On the drivers side I used the factory nipple that is sticking out of the bottom of the hard pipe for this connection. Since I have a boost controller and I was not using that nipple. Seemed like a perfect setup, but as stated water will get in the line and travel to the control module. And I had thought about the control module coming on early is probably contributing to the amount of water getting into the sense line. I guess I need to contact Snow Performance about the control module coming on too early, because it sounds like a defective module.
