Abstract
A grommet for sealing the wires extending through the wall of a fuel tank is formed by first removing a portion of the covering exposing the strands of wires within. A liquid sealing agent is applied to the strands and the strands are compressed to displace the strands. A hardener is then applied and then the strands are encapsulated in the body of the grommet.
