Stainless steel needles are supplied with a purchase a N-EVAP. Install the needles into the luer fittings at the bottom of the valve tube assembly by rotating the needle half turn. Do not over tighten. Raise all valve tubes to their highest position. Turn all needle valves on the valve tube assembly off by rotating clockwise.
