A heating element
1. Remove the fuel filter as described in Chapter Maintenance.
2. Disconnect the electrical wiring, then unscrew the center bolt and remove the heating element from the base of the fuel filter housing. Remove the sealing ring that is installed between the element and the filter housing; it is to be replaced.
3. When installing, position the new O-ring in the groove in the heating element and install the element into the filter housing, tightening the center bolt securely.
4. Connect electrical wiring and install the fuel filter as described in Chapter Maintenance.
Thermal switch
1. Disconnect the wiring connector from the thermal switch.

Remove the sealing washers that are located on each side of the fuel hose connector. Discard the washers - they must be replaced.
3. Installation is carried out in the reverse order. Be sure to install new sealing washers on each side of the fuel hose connector.
