worst case even if the crimping on the hose is bad, you can see if there is an industrial hose supplier in the area that can recrimp it or just run two 28 inch spg hoses and bungee them down to the tank.
thanks, the latter is the fall back plan. I found a single 28" HP hose in a store earlier in the week, and I have another with me in my save-a-dive kit, so something'll work out.
but hoping it can just be rebuilt when I can get hold of some O2 compatible grease when the stores are open tomorrow
