I am replacing the suction discharge hose on the AC system of a 1998 Dodge Ram and on the side where the AC Filter is at the fitting is a tight fitting. Any idea how that fitting comes apart.   It is a clamp style of fitting, which is not the problem to get off, but to remove the suction/discharge hose after that fitting is off is another question. Any thoughts.
