It could be leaking where the hose is clamped on to the fitting, or maybe the fitting needs to just be tightened a bit, or maybe the fitting has a small crack. Since it isn't PEX hose there, you could remove the crimped on clamp (dikes, Dremel tool?) and reattach the hose with a standard screw-tightened hose clamp. I would trim of 1/2 to 1 inch of the hose end before reattaching it.
But I think it would be wise to determine exactly where it's leaking before you tear into it. Pressurize the system, lay on the floor and watch it. Maybe a mirror and flashlight would help. Try dabbing a wad of dry toilet paper onto different spots to see where the water is escaping- might help in isolating the problem.
Good luck. Might not hurt to go ahead and buy a new fitting and teflon tape AND the hose clamp before you start tearing it apart. That way you'd be set no matter what the problem.
