I have come across some issues with these systems that current owners will need to address.
1) I highly recommend a purge system. This is a simple connection that puts a momentary button that jumpers between the main red power input to the controller and the green pump circuit. This will be highly useful in determining that the system is functional AND it will purge the lines of air. If the system hasn't been used in awhile and/or you have long lines you will find that the engine will have a tendency to slowly siphon off all the fluid from between the solenoid and the nozzles. It can take 3-5 seconds of spraying to purge the lines of air depending on how long they are. For this reason I also recommend placing the solenoid as close as possible to the nozzles.
2) The pumps are not waterproof. Snow does not make any specific recommendations about mounting the pump but it has come to my attention that they need to be protected from splash water and rainfall. If you can't find a suitable mounting location then I suggest covering the pump in a plastic shield or bag so that it does not receive direct spray or dripping from any water source. Behind the fenderliners is not sufficiently dry to prevent possible corrosion and failure.
3) Anyone who does not have dual nozzles on their system I highly recommend it.
4) Snow now has their flow monitoring device available so for ultimate safety that is something which should be looked into.
Any questions, please post.
