Sonicate or soak the new seal in isopropanol for 15 min to clean and provide lubrication for installing.
Place the replacement seal on the rod-shaped end of the seal insertion/removal tool so that the spring is visible when the seal is fully seated on the tool.
Insert the tool into the pump head so that the open side of the seal enters first, facing the high-pressure cavity of the pump head.
Be careful to line up the seal with the cavity while inserting. Withdraw the tool, leaving the seal in the pump head.
When you look into the pump head cavity, only the polymer portion of the seal should be visible.
