I am looking to replace all the rule and oil vent lines in my 1972 911 (MFI) with OEM parts. I'm looking for the ones that lead from the engine bay to the charcoal canniseptermand vent tank, as well as the larger oil vent hoses that go from the engine bay to the oil tank. Anyone know where to buy them? Meterware would be fine, but ai just don't know who sells it. I'm using all the part numbers from the PET, but they seem to have been superseded numerous times... Thanks for your advice.
