1. Safety First:
* Disconnect the battery's negative terminal. This prevents accidental sparks that could ignite fuel vapors.
* Ventilate the area. Work in a well-ventilated space or outdoors to avoid inhaling fuel fumes.
* Have proper safety equipment. This includes eye protection, gloves, and potentially a fire extinguisher.
2. Preparation:
* Gather tools: You'll need jack stands, jack, socket set (including various sizes), wrenches, fuel line disconnect tools, and possibly a fuel pump removal tool (depending on the design). A siphon pump can help remove fuel from the tank.
* Consult a repair manual: A Haynes or Chilton manual for your specific year and model Fiero will be invaluable. It will show you exact locations of components and provide detailed instructions.
3. Dropping the Fuel Tank:
* Raise the vehicle securely: Use jack stands to support the car after lifting it with a jack. Never work under a car supported only by a jack.
* Locate the fuel tank straps and fuel lines: These are typically located at the rear of the vehicle, under the car.
* Drain the fuel tank: Use a siphon pump to safely remove as much fuel as possible. This makes the tank much lighter and easier to handle. You'll need a suitable container to collect the fuel. Dispose of it properly according to local regulations.
* Disconnect the fuel lines: Carefully disconnect the fuel lines using appropriate tools. You'll likely have fuel supply and return lines. Have rags handy to soak up any spilled fuel. Some people use clamps to temporarily prevent fuel from flowing.
* Disconnect the electrical connector: This connects to the fuel pump.
* Disconnect the tank straps: Carefully loosen and remove the straps holding the fuel tank in place.
* Lower the fuel tank: Carefully lower the tank. It might be heavy, even after draining, so be prepared. Consider using straps or a helper.
4. Accessing the Fuel Pump:
* Once the tank is lowered, you should have access to the fuel pump assembly. This is typically located on top of the tank. Consult your repair manual for the precise location and removal procedure.
* Remove the fuel pump assembly: This may involve removing a retaining ring, bolts, or other fasteners. Again, your repair manual will provide guidance. Often there's a cover over the pump itself.
5. Reassembly:
Reassembly is the reverse of the removal process. Make sure all connections are secure, and double-check your work before lowering the tank and starting the car.
Important Considerations:
* Fuel is highly flammable. Exercise extreme caution throughout the entire process.
* The fuel tank can be heavy. Have a helper or use appropriate lifting devices.
* If you are not comfortable performing this repair yourself, take your Fiero to a qualified mechanic. This is a somewhat involved procedure and improper handling can lead to injury or damage.
This is a general outline. Always refer to a repair manual specific to your 1986 Pontiac Fiero SE 2.8L V6 for detailed, step-by-step instructions and diagrams. Safety is paramount; if you're not comfortable working on cars, leave it to a professional.
