断开两个电池上的负极电缆。把燃料箱的油排到一个批准的容器里。安全地抬起并支撑车辆以进行燃料箱移除。适当地支撑油箱。断开加油口颈和排气软管。拆下将填料颈固定在车身上的4个螺栓。拆卸填料颈,检查是否有霉菌或腐蚀。请根据需要更换填料颈。拆下固定油箱的两根带子。稍微降低油箱以访问泵电气连接器和软管。 Disconnect the fuel pump electrical connectors and fuel lines. Clean the top portion of the fuel tank to prevent fuel tank contamination. Unscrew the fuel pump retainer ring. Remove the fuel pump from the tank. Be careful as the pump bowl will be full of fuel. Inspect the fuel tank for contamination and clean if necessary. Carefully read all the instructions before proceeding with the installation. Install a new rubber gasket to the fuel tank opening and insert the fuel module. The module top cover has an index groove that must be aligned with the fuel tank marking. Remove the old quick connect retainer clips from the module and install to the new pump. Inspect the fuel tank straps and replace as necessary. Lift the fuel tank high enough to connect the fuel pump electrical connector and hoses. When installing the fuel lines, make sure you hear a good click making sure the fuel line is well connected. Now position the fuel tank and attach the two straps to the frame. Reconnect the filler neck and vent tube hoses. Fill the tank halfway with clean fuel to ensure proper pump priming. Reconnect both batteries negative cables. Before starting the vehicle prime the fuel system by cycling the ignition switch several times. With the fuel system now under pressure, perform an undercar visual inspection for leaks.
