   WARNING Do not handle the fuel sender assembly by the fuel pipes. The amount of leverage generated by handling the fuel pipes could damage tool Joints.
   
   
6. Disconnect the fuel and evaporative emission (EVAP) lines from the fuel tank module.
   

• Fuel sender assembly retaining ring using a fuel tank sending unit wrench. Remove the fuel sender assembly and the seal. Discard the seal.
  
• Note the position of the fuel strainer on the fuel sender. Support the fuel sender assembly with one hand and grasp the strainer with the other hand. Pull the strainer off the fuel sender. Discard the strainer after inspection. Inspect the strainer. Replace a contaminated strainer and clean the fuel tank.
  
• Fuel pump electrical connector
  
• Electrical connector retaining clip from the fuel level sensor
