The fitting on the left (the black one) is a restrictor fitting i bought from ACS for the oil pressure port on my O-320.
The engine came from Aero Sport with the fitting on the right. That fitting does not have the obvious pinhole restriction on the pipe-thread end like the black one does, but it does appear to have somewhat of a restriction on the flared end. Are these just different types of restrictor fittings, both equally suitable for the oil pressure port?
