Leaking Monovalve.....Repair Kit?

I've searched the threads and coudn't find anything specific to my problem. It's a simple question (or series of questions) really. Anybody think the repair kit that fastlane sells would fix a leaking mono valve? Is it the seals that fail on the valve? If it is the seals does the mono valve kit include the seals? Thanks in advance for the help!

Based on one man's experience, with one monovalve, the problem comes from either a torn diaphragm or fouled screen. See this site for pictures:
