Diesel fuel filter

摘要

A diesel fuel filter has a filter element which incorporates or is constituted by a heater made of an electrically conductive fabric which heats at least the inlet side surface of the filter element. A filter element formed entirely from the electrically conductive fabric can be used to protect a lift pump 12 while a filter element made of layers of fine mesh filter material and an electrically conductive material of coarser mesh is better suited for the primary fuel filter 16 located upstream of the fuel injection pump 18.
