2003 Ford Focus Fuel Tank Parts Q&A

• Q: What precautions should be taken when servicing the fuel tank unit to avoid personal injury on 2003 Ford Focus?

  A: The fuel tank unit servicing demands prohibition of both smoking and carrying lighted tobacco items along with open flames because highly flammable vapors present in the system can ignite leading to personal injury. Before any fuel work start you must prepare for liquid flow while maintaining proper fuel safe practices. The replacement procedure demands a new assembly instead of aftermarket sleeving or re-adhering loose materials when a liquid or vapor tube requires replacement. The process for reusing liquid or vapor tube connectors begins with compressed air cleaning of the connector retaining clip area followed by engine oil application to the tube end before connection. The first step involves opening fuel system pressure followed by emptying the fuel tank contents. Position the vehicle at neutral and hoist it before removing its fuel tank. A quick-release tab should be pressed to disconnect the fuel tube after which a suitable fuel pump lock ring remover helps to rotate the lock ring counterclockwise until the module becomes free for removal. Keep the locking ring and seal for disposal. Check that the float and arm stay unharmed when following this procedure. Installation should begin with the same reverse order of removal while inspecting the fuel pump module flange and fuel tank O-ring contact surfaces for damage because any alterations will be detrimental to installation. Any fuel pump module or fuel tank replacement is required when the fuel O-ring contact area shows bending scratches or corrosion. New O-rings and lock rings should be used for fuel pump module installation while clean engine oil must lubricate the tube fittings before alignment by pressing to establish full engagement.
