  1. Relieve the pressure from the fuel system as described in "Relieving Fuel System Pressure" located in this section.
  3. Disconnect the battery negative cable.
  5. Slide the fuel line clamps back off the connections on the filter. Then, slowly pull one connection off just until fuel begins to seep out. Place a small plastic container or stuff a couple of rags under the filter to absorb any excess fuel.
  7. Pull both fuel hoses off the connectors. Remove the filter from the clamp. On some models, it will be necessary to unbolt the fuel filter from the mounting bracket.
