Fuel Gauge Sending Unit

You should start by discharging fuel system pressure then disconnecting the negative battery cable for 90 seconds to avoid Air Bag activation during service of the fuel level sensor. First remove the rear seat cushion assembly for any seat type configuration before moving to the rear floor service hole cover. The maintenance sequence begins with separating the sub-assembly and later removing three assemblies which include the vent tube set plate followed by the fuel suction tube assembly with its pump and gauge and then ending with the fuel level sensor assembly. Sort the replacement order by first installing the fuel level sensor assembly then the fuel suction tube assembly with pump and gauge and finalizing with the fuel tank vent tube set plate. Connect the fuel pump tube sub-assembly before reestablishing the cable connection to the negative battery terminal and verify fuel leak points. Repair work ends with installing the rear floor service hole cover together with the rear seat cushion assembly of fixed or fold-down or reclining seat varieties.

The removal process of a fuel level sensor requires fuel system pressure discharging. Users should disconnect the negative battery terminal cable before waiting for 90 seconds to preserve Air Bag function. The following procedure dictates that the rear seat cushion assembly should be removed according to different seat configuration types: fixed seats, fold-down seats and reclining seats. Continue by taking off the rear floor service hole cover before you can separate the fuel pump tube sub-assembly and remove the fuel tank vent tube set plate. You must disconnect the fuel suction tube assembly along with its components before taking out the fuel level sensor assembly.

A proper service of the 2AZ-FE Fuel Level Sensor Assembly starts with fuel system pressure release and negative battery terminal cable disconnection. To work on the Coupe you must take out its rear seat cushion assembly while Convertible owners must also eliminate the rear seat cushion assembly. The service begins by removing the rear floor service hole cover before separating the fuel pump tube sub-assembly then taking out the fuel tank vent tube set plate. First remove all components of the fuel suction tube assembly with pump and gauge and next get rid of the fuel level sensor assembly. The main steps for installation include putting on the fuel level sensor assembly followed by the fuel suction tube assembly with pump and gauge and finishing with the fuel tank vent tube set plate. Connect the fuel pump tube sub-assembly to the negative battery terminal by attaching the cable while initialization steps may be necessary after reattaching the cable. Check for fuel leaks before putting back the rear floor service hole cover as well as the rear seat cushion assembly which applies to both Coupe and Convertible models.
