It should hold, both the res and the dual stage elements. If I remember right, the res on the 201 is behind the r/h inner fender liner. I do know the line that is kinda under the battery tray will corrode and leak as well as the heater control valve diaphram. (under the r/h cowl.) Dual elements should hold individually, replace any that leak.
