3. REMOVE FUEL TANK PRESSURE SENSOR (VAPOR PRESSURE SENSOR ASSEMBLY)

(a) Remove the tube joint clip and pull off the fuel tank pressure sensor (vapor pressure sensor assembly) from the fuel tank assembly.

NOTICE:

  • Remove any dirt or foreign matter on the fuel tank pressure sensor (vapor pressure sensor assembly) before performing this work.
  • Do not allow any scratches or foreign matter to get on the parts when disconnecting them as the fuel tank pressure sensor (vapor pressure sensor assembly) has an O-ring that seals the fuel suction plate sub-assembly.
  • Perform this work by hand. Do not use any tools.
  • If the fuel suction plate sub-assembly and fuel tank pressure sensor (vapor pressure sensor assembly) are stuck, carefully wiggle or push and pull the fuel tank pressure sensor (vapor pressure sensor assembly) to release it. Pull the fuel tank pressure sensor (vapor pressure sensor assembly) off the fuel suction plate sub-assembly carefully.
