摘要:
A fuel filter for a motor vehicle includes a housing made of a base Nylon 12 material to which are added stainless steel fibers to render the housing electrically conductive while retaining moldability. The electrically conductive housing permits charges generated by the fuel passing through the filtering media to be dissipated to the vehicle body, thereby preventing erosion of the housing and subsequent leaks.
