### Summary
Replacing the fuel tank in a 3S-GTE equipped Toyota Celica requires draining the fuel, disconnecting lines, and removing the tank. This task should be undertaken with caution due to the flammable nature of fuel and pressurized lines.
### Likely Causes / Decision Path
1. Fuel tank has structural damage or leaks.
2. Fuel pump failure due to tank debris or corrosion.
3. Fuel system contamination from a damaged tank.
### Quick Checks (5–10 min)
– Confirm the tank leaks by inspecting for damp spots under the tank.
– Check fuel lines and connections for any visible damage.
– Ensure the fuel gauge is functioning correctly.
### Detailed Procedure
1. **Preparation**:
– Gather tools: jack, jack stands, basic hand tools (socket set, wrenches), fuel line disconnect tool, safety goggles, gloves, and a fuel container.
– Ensure you are working in a well-ventilated area away from open flames.
2. **Safety Steps**:
– Disconnect the negative battery terminal.
– Relieve fuel system pressure by removing the fuel filler cap and using a fuel pressure gauge or simply disconnecting the fuel pump relay.
3. **Drain Fuel**:
– Use a fuel siphon or pump to remove fuel from the tank into the safety container. Dispose of properly.
4. **Remove the Fuel Tank**:
– Raise the rear of the vehicle using a jack and place jack stands under the frame for safety.
– Locate the fuel tank straps that secure the tank; remove the bolts securing the straps using the appropriate socket.
– Disconnect all fuel lines, electrical connectors for the fuel pump (if applicable), and any other attachments.
– Support the tank from beneath while removing any additional supports or brackets.
– Carefully lower the tank out of the vehicle.
5. **Install New Tank**:
– Position the new fuel tank into place and reattach the tank straps loosely.
– Reconnect all fuel lines and electrical connectors.
– Ensure that all connections are secure and that there are no kinks in the fuel lines.
6. **Secure the Tank**:
– Tighten the fuel tank straps to secure the tank in place.
– Double-check connections for leaks.
7. **Testing**:
– Reconnect the battery terminal.
– Turn the ignition key to the “ON” position (without starting) to prime the fuel system and check for leaks from all connections.
– Start the engine and monitor for any signs of leaks or issues.
### Specifications
– **Fuel Line Torque**: Typically around 13-18 ft·lbf (18-25 N·m), but check manufacturer specs for your specific model.
– **Fuel Tank Strap Bolt Torque**: Often around 26-34 ft·lbf (35-46 N·m), verify in the service manual or specific guides.
### Notes & Safety
– Always dispose of old fuel and the old tank in accordance with local regulations.
– Be cautious of fuel vapors; they are hazardous.
– Ensure the vehicle is securely supported on jack stands before working underneath.
### If Unresolved
If you encounter issues during the procedure such as stubborn bolts, or if you need further details about securing specific fuel lines, please mention any additional symptoms or outcomes you observe.
