Ok, so i have been considering this as preventive maint. After researching the install video's on the all mighty u tube it seems that the feed/return line QD'S are just as likely to fracture at the plastic union as the "T" connector? Since we would have to adapt to the driver heater core with hose and clamps would it be wise to eliminate the QD'S entirely and simply run standard heater hoses for the feed/return lines to the "T" and from the "T" to the rear passenger core metal lines???. The OE hose's are like $50 to $70 each and still have the weak QD.
