Safety Precautions
Before beginning any work, ensure the vehicle is parked on a level and stable surface and that the parking brake is engaged. Wear safety glasses and gloves to protect yourself from any potential hazards. Disconnect the negative terminal of the battery to prevent electrical shock. Allow the engine to cool completely before starting any repairs to avoid burns.
Step-by-Step Instructions
1. Remove the Fuel Tank
Locate the fuel tank under the rear of the vehicle. Use an 8mm socket wrench to remove the bolts holding the fuel tank skid plate in place. Carefully lower the fuel tank using a floor jack or a helper. Be cautious not to damage the fuel lines or electrical connections.
2. Disconnect Electrical Components
Disconnect the electrical connector on top of the fuel pump assembly by gently squeezing the tabs on the sides of the connector and pulling it straight up. Unplug the fuel level sensor connector located on the side of the fuel pump assembly.
3. Remove the Fuel Pump Assembly
Use a 10mm socket wrench to remove the bolts holding the fuel pump assembly to the fuel tank. Carefully lift the fuel pump assembly straight up to remove it from the tank. You will encounter a small amount of fuel spillage during this step.
4. Install New Fuel Pump Assembly
Insert the new fuel pump assembly into the fuel tank, aligning it with the mounting points. Secure the assembly with the 10mm bolts and tighten them using a socket wrench.
5. Connect Electrical Components
Plug in the fuel level sensor connector and reconnect the electrical connector on top of the fuel pump assembly. Ensure that the connectors are fully seated and secure.
6. Reinstall Fuel Tank
Carefully lift the fuel tank back into place and secure it with the bolts using an 8mm socket wrench. Tighten the bolts to the specified torque.
7. Reset Battery and Test
Reconnect the negative terminal of the battery. Start the vehicle and listen for any unusual noises or leaks. Check the fuel gauge to ensure it is functioning properly.
