about 150 190 degrees and about 160 degrees as shown the pump air passageway 43 44 is comprised of a tube body formed of a resilient flexible material such as plastic elastomer or rubber compounds and is capable of withstanding repeated deformation cycles when the tube is deformed into a flattened condition subject to external force and upon removal of such force returns to an original condition generally circular in cross section the tube is of a diameter sufficient to operatively pass a volume of air sufficient for the purposes described herein and allowing a positioning of the tube in an operable location within the tire assembly as will be described preferably the tube has a circular cross sectional shape although other shapes such as elliptical may be utilized the tube may be a discrete tube that is inserted into the tire during tire manufacturing or the tube may be molded into shape by the presence of a removable strip that forms the passageway when removed as shown in fig2 a an inlet filter assembly 600 is connected to a regulator assembly 300 for providing inlet filtered air to the regulator assembly 300 the regulator assembly is connected to the inlet end 42 of the first pump passageway 43 via an inlet banjo fitting 100 the first pump passageway has an outlet.
