I'm intrigued. Do tell more. I was looking at the setup at a local dive shop for $300 that has a 50 ft hose, 1st & 2nd stage regulators, but it looks like the cheap yellow octopus regulator.
Go to your local welding supply and buy a 50' oxygen hose with female oxygen fittings, 2 replacement female fittings and 2 double end male oxygen fittings. Cut the hose between your first and second stage and put the replacement fittings on each end of the hose you cut then you can use the male fittings to connect the 50' hose between the first and second stages. You will want to tape a life line to the hose that connects to your harness or belt and to something in the kayak. This will have you pulling the kayak by the line not the hose. The hose should cost about $50 and maybe another $15-20 for the fittings.
