Last summer the hoses in my tank failed to the degree that my bike would start but not run. I knew it was a pressure problem but when I opened the tank and visually inpected the hoses it appeared that the hoses had merely some fine cracks in them,
After overhauling everything it the tank (it was due) I cut the hoses open. Only then could I see the extent of the damage.
