Brad,
Those are the Rule 1100's that are the industry standard. That blue thingy is a solenoid valve, did you add it or is it stock? Either way, can you read a manufacturer and part number off of it?
When I was in the Nav and stationed in Vallejo, we used to go up to Berryessa and jump off the big rock. I swear, it had to be a 75 foot drop. Can someone snap a pic of that thing? My kids don't believe me!
