16 FUELSYSTEM2.2LDICOR Fig. 18 Fig. 19 Fig. 20 FUELTANKSTRAINER It is located inside the fuel tank. (Fig. 18) Removal Unscrew banjo bolt and disconnect suction line from fuel tank strainer. Unscrew hex screws and pull out strainer. Inspection Check strainer mesh for clogging. Assembly Clean strainer and refit with a new ‘O; ring. Connect suction line to fuel tank strainer and tighten banjo bolt to specified torque. Always use new sealing washers. Prime fuel system as mentioned above. Fuel Gauge tank Unit Removal: Remove electrical connections. Remove 6 screws securing Float unit from the fuel tank. Remove the seal from the unit. Fitment: Please follow the reverse procedure of Assembly When installing fuel tank gauge, ensure that fuel tank gauge unit assembled with ‘O’ ring in place. Testing /Checking: (Fig. 20 & 21) The sender is a float operated rotary potentiometer. Which provides a variable resistance to ground for the output from the gauge. When the sender float is at its lowest point, indicating an empty fuel tank, the resistance to earth is at its lowest. The resistance sensed by the gauge, which positions the needle accordingly. Use ohm-meter to confirm that the resistance of the fuel level sensor (Fuel Tank Unit) change with the level of float position.
