I have an FI 124 in which all the hoses are rotted. I have no issue with the rest of the various kinds of clamps, however these collars that are located all over the FI system are killing me, let alone on a barbed hose end. I've tried heating them up, as well as taking an angle grinder to them, to no avail. HELP. I think I can already hear(read?) bugsymike coming to the rescue.
