In the vintage air bulkhead fittings, do you use the orings on the heater sides that fit into the fitting? Or are they supposed to seal without any oring? It does seem there where extra in the bags but the ac ones had them installed and coolant ones had none. Plus the end that fits into the bulkhead fittings are shorter on the coolant fittings.
