I had to replace mine when it broke below the regulator. I had had the supercharger off once, and replaced the IMGs once, and the original supercharger makes 3 times that that hose was flexed a lot. It just fatigued enough to develop a leak. Anyway I ended up bypassing it as I could not get a tool in there to remove what was left of the hose. My new hose runs around the top instead of between the engine and the firewall.
