Unit inspection

  1. Fuel sender gauge ASSY check (fuel sender gauge main)
    1. Visual inspection
      1. Check the fuel sender gauge ASSY for damage.
      2. Check the dimensions between the float and fuel tank seating surface when the float is at F (upper limit) and E (lower limit).
      DIMENSION SPECIFICATION

      Float position F (upper limit) - fuel tank seating surface 121 to 129 mm {4.76 to 5.08 in}
      Float position E (lower limit) - fuel tank seating surface 14.7 to 22.7 mm {0.579 to 0.894 in}

    2. Resistance check
      WARNING: Be careful of fire.
      1. Check that the float moves smoothly between the positions F (upper limit) and E (lower limit).
      2. Check the resistance between the connector terminals when the float is at F (upper limit) and E (lower limit). Also check that the resistance varies continuously.
      RESISTANCE SPECIFICATION

      Inspection terminals Inspection conditions Standard value
      1 - 2 Float position F (upper limit) 6.5 to 8.5 Ω
      Float position E (lower limit) 168 to 172Ω

  2. Fuel sender gauge ASSY NO. 2 check (fuel sender gauge sub)
    1. Visual inspection
      1. Check the fuel sender gauge ASSY NO. 2 for damage.
      2. Check the dimensions between the float and fuel tank seating surface when the float is at F (upper limit) and E (lower limit).
      DIMENSION SPECIFICATION

      Float position F (upper limit) - fuel tank seating surface 148.8 to 157.8 mm {5.86 to 6.21 in}
      Float position E (lower limit) - fuel tank seating surface -1.3 to 7.7 mm {-0.05 to 0.30 in}
