Oh and the o-ring seals about the mouthpiece swivels are a constant source of aggravation. Get rid of them. o_ring modification (bottom pic)

The Oxygauge problem can be fixed with the silicone PO2 gauge (third pic enlarged), or better yet get rid of the Oxygauge

Punctures in the CL's are common, just get some Tear-aid Type A and they disappear. (Tear-aid can be gotten from Cabela's Official Website - Quality Hunting, Fishing, Camping and Outdoor Gear at competitive prices. Part # IH516557

BTW, converting a Dolphin to MCCR can cost less than 500 USD with a little planning and looking at all the different approaches taken. Don't rush into it though. Get some experience in SCR and if it is to be, the step to the dark side will become evident.
