Fuel Sub Level Sensor: Installation

Install the fuel sub level sensor to the fuel tank.
1. Make sure the sealing portion is free from fuel or foreign matter before installation.
2. Align the cutout (B) as shown in the figure, and install the fuel sub level sensor upper plate cushion to the fuel sub level sensor upper plate.
3. Align the cutout of the fuel sub level sensor upper plate with the protrusion (B) of the fuel sub level sensor as shown in the figure, and install the fuel sub level sensor upper plate from the upper side of the fuel sub level sensor.
4. Install the gasket from the lower side of the fuel sub level sensor so that the protrusion (B) of the fuel sub level sensor and the protrusion (A) of the gasket are positioned as shown in the figure.
  NOTE: Use a new gasket.
5. Install the fuel sub level sensor to the fuel tank in the direction shown in the figure, and tighten the nuts to the specified torque in the order as shown in the figure.
  CAUTION: Set the arm and float of the fuel sub level sensor while paying attention to prevent them from contacting the fuel tank. If the arm of the fuel sub level sensor is bent, the fuel gauge may not read correctly.
