Sealed fastener cap and related method of manufacture

A method of using a fastener cap system, the method comprising:

• moving a first rigid cap along a cap feeder, the first rigid cap including a sealing member;
• and
• engaging a cap lowermost surface of the first rigid cap slidably with a ramp of the cap feeder, without the sealing member extending downward from the first rigid cap and engaging the cap feeder, in a pre-installation mode, as the first rigid cap moves along the cap feeder,
• wherein the sealing member includes a sealing member lower surface that is disposed above the cap lowermost surface in the pre-installation mode and at the same level as the cap lowermost surface in an installed mod in which a fastener engages the first rigid cap with a substrate.
