Fuel Pump

Following safety rules becomes essential for servicing the fuel gauge sender and fuel pump module since these components contain highly flammable mixtures. Always maintain a safe distance from any open flame because smoking or using personal electronic devices is completely forbidden during maintenance tasks. Additionally to this you need to drain all fuel pressure before starting the job for fuel safety purposes. Disconnecting the battery ground cable is mandatory for any work on evaporative emission systems along with fuel-related components. A vehicle equipped with fire suppression requires depowering the system before starting any servicing work. Start the task by taking out the fuel tank assembly. The first step is to remove the fuel pump module harness from the fuel tank pressure sensor after releasing its two wiring harness retainers. Remove all foreign matter along with dirt from the fuel pump module mounting flange and its adjacent area. The fuel pump module requires careful handling to preserve both the float arm and filter while the technician removes its six bolts which should be retightened to 10 Nm (89 lb-in) when reassembling the component. Discard the old fuel pump module seal after visual inspection of the flange and seal contact surfaces for damage while avoiding any adjustments or polishing of these areas. Follow the removal steps in reverse to install the new fuel pump module with the seal before tightening bolt connections to 10 Nm (89 lb-in). After conducting the service you must repower the vehicle when it has a fire suppression system installed in it.

Service of both the fuel gauge sender and fuel pump module needs strict safety precautions due to the dangerous flammable fuel mixtures inside these components. Before unpacking fuel tubes or components always verify fuel system pressure release and stay away from personal electronic devices and smoking since they might cause unwanted fuel spray. Cable grounding of the battery must always happen before performing maintenance on the evaporative emission system or any fuel-related components. Start by separating the fuel tank followed by unharnessing the fuel pump module from the pressure sensor before releasing its two harness retainers. You should perform a cleaning process on both the fuel pump module mounting flange as well as its surrounding region to eliminate all foreign matter and dirt. Treatment of the fuel pump module should be gentle because it affects the float arm and filter mechanism and after that you must remove all six securing bolts. After module extraction personnel should dispose of the previous fuel pump module seal followed by a thorough inspection of the seal contact surfaces and the flange for damage. It is essential to avoid adjusting these areas as well as any polishing attempts. The fuel pump module requires replacement alongside the fuel tank in case of damage. Replace the fuel pump module seal and follow the reverse steps for reinstallation by tightening bolts to 10 Nm (89 lb-in).

The servicing of the fuel level sensor and fuel pump module requires extreme caution because highly flammable mixtures exist in the area. The service requires you to stop using electronic devices near flammable mixtures as well as drain fuel system pressure before tube removal to avoid fuel leaks. The battery ground cable must always be disconnected while performing maintenance of fuel-related components or evaporative emission system operations. Start by unmounting the fuel tank from its installation location. The operation begins by disconnecting the fuel pump module harness from the fuel tank pressure sensor while simultaneously releasing its two wiring harness retainers. Wipe down the fuel pump module mounting flange together with the bordering area because foreign debris must be eliminated. When handling the fuel pump module normalize caution to protect both the float arm and filter and then unscrew the six mounting bolts from the module. The old fuel pump module seal needs disposal while the technician checks to ensure the flange and seal contact areas show no signs of breakage and avoids adjusting or polishing these points. Any damage to surface areas of the fuel pump module or fuel tank requires either a new fuel pump module or a new fuel tank installation. Return the bolts to 10 Nm (89 lb-in) after installing a new fuel pump module seal while performing the reverse order of the removal process.

Observation of safety measures becomes essential in fuel level sensor and fuel pump module servicing because these components contain dangerous flammable substances. The technician must refrain from smoking and must uninstall any fuel components only after dropping the fuel system pressure to prevent hazardous fuel release. The disconnect of the battery ground cable must be completed for all work performed on the evaporative emission system and fuel-related components. Servicing any vehicle which contains a fire suppression system starts with depowering it using stated procedures. Start the procedure by taking out the fuel tank. The task begins with releasing the two wiring harness retainers which allows you to disconnect the fuel pump module harness from the fuel tank pressure sensor. Remove all foreign materials from the fuel pump module flange as well as the surrounding area before continuing. When handling the fuel pump module keep both the float arm and filter protected from damage while you remove the six bolts using 10Nm (89lb-in) torque at reinstall. The service technician should throw away the previous fuel pump module seal while checking the flange and seal contact surfaces for damage since these areas should remain untouched. Usage of a new fuel tank module or fuel tank becomes necessary in case damage occurs. Reverse the removal steps when installing the new fuel pump module seal. End the service and activate vehicle power only after completing fuel tank service on cars equipped with fire suppression systems.
