Best heater control valve to head pipe hose size?
Other than OEM, what standard size heater hose best fits the stock heater control valve to head exit pipe? Local auto supply stores have only 5/8" and 3/4" ID heater hose, but 5/8" seems too tight and 3/4" a bit loose, so what size is best to both fit the heater control valve and the head pipe?
