1. Safety First:
* Disconnect the negative battery cable. This is crucial to prevent sparks near gasoline fumes.
* Ventilate the area. Work in a well-ventilated space or outdoors. Gasoline fumes are highly flammable and dangerous.
* Wear safety glasses and gloves. You'll be working with sharp edges and potentially messy fluids.
* Have proper tools ready before you begin. Improper tools can lead to damage or injury.
2. Preparation:
* Locate the fuel tank: It's typically under the rear of the vehicle.
* Consult a repair manual: A Haynes or Chilton manual specific to your 1995 S10 Blazer is highly recommended. It will provide detailed diagrams and instructions specific to your vehicle's year and model. This is crucial for accurate steps and avoiding damage.
* Gather necessary tools: This will likely include various sockets, wrenches, screwdrivers, jack stands, a fuel pump disconnect tool (may be needed), and potentially a fuel tank strap wrench.
3. Fuel System Disconnection:
* Release fuel pressure: This is important to prevent fuel spraying. Consult your repair manual for the precise procedure. It might involve disconnecting the fuel pump relay or cycling the ignition switch.
* Disconnect the fuel lines: Carefully disconnect the fuel lines from the tank. This usually involves using a line disconnect tool to prevent fuel spillage. Have rags ready to absorb any spilled fuel. Mark the lines to ensure proper reinstallation.
* Disconnect the fuel tank vent line. This is a smaller hose that allows pressure equalization in the tank.
* Disconnect the fuel sender unit electrical connector. This usually has a locking clip.
4. Removing the Fuel Tank:
* Secure the vehicle: Use jack stands to securely support the vehicle after raising it. Never work under a vehicle supported only by a jack.
* Remove the fuel tank straps: These straps hold the tank in place. They might require loosening or removal of bolts or nuts. Use the appropriate tools to avoid stripping or damaging the hardware. A fuel tank strap wrench is helpful here.
* Lower the fuel tank: Carefully lower the tank. It may be heavy and awkward, so have assistance if possible. Be aware of any other components that might interfere with its removal.
* Disconnect any remaining connections: There may be other connections to disconnect depending on your specific vehicle. Refer to your repair manual.
5. Reinstallation (Reverse Order):
* Reinstallation is essentially the reverse of removal, but pay close attention to detail.
* Ensure all connections are secure.
* Reconnect the battery's negative terminal last.
Important Considerations:
* Fuel is flammable and hazardous. Exercise extreme caution.
* The fuel tank is heavy. Have a helper if necessary.
* This job can be challenging. Don't hesitate to seek professional help if you're not comfortable doing it yourself.
This is a general guide. Always consult a repair manual specific to your 1995 S10 Blazer for precise instructions and safety precautions. The specific steps may vary slightly depending on your vehicle's configuration. Improperly removing the fuel tank can lead to damage to your vehicle or injury to yourself.
