Here's a general outline. Specific steps and procedures may vary slightly depending on the exact model and engine (V6 or V8). Consult a repair manual specific to your 1991 Camaro RS for detailed, illustrated instructions and torque specifications. This is not a substitute for a professional repair manual.
Tools You'll Likely Need:
* Socket set (metric)
* Wrenches (metric)
* Screwdrivers (Phillips and flathead)
* Fuel pump pliers or special tool (to disconnect fuel lines)
* Fuel line disconnect tool (may be needed)
* Jack and jack stands (essential for safety)
* Wheel chocks
* Safety glasses
* Gloves
* Rags or shop towels
* New fuel pump (ensure it's the correct one for your vehicle)
* New fuel filter (recommended to replace at the same time)
* Possibly a fuel pressure gauge (to verify correct pressure after installation)
General Steps:
1. Safety First: Disconnect the negative battery terminal.
2. Access the Fuel Pump: This usually involves dropping the fuel tank. The process varies by model, but generally involves:
* Raising the rear of the car using a jack and securing it with jack stands.
* Removing the access panel under the rear seat (if applicable).
* Locating and disconnecting the fuel tank straps (usually bolts).
* Carefully lowering the fuel tank. You may need to support it with a fuel tank strap or a jack. Be prepared for fuel spillage; have rags handy.
3. Disconnect Fuel Lines and Electrical Connectors: Carefully disconnect the fuel lines using fuel line pliers or the appropriate disconnect tool. Note the orientation of the lines and take photos if needed to ensure correct reconnection. Disconnect the electrical connectors to the fuel pump.
4. Remove the Fuel Pump Assembly: The fuel pump is usually housed in a module within the fuel tank. This assembly will need to be removed. It may involve unbolting the assembly from the top of the tank or from the bottom, depending on your vehicle's design. Refer to your repair manual for exact instructions.
5. Replace the Fuel Pump and Filter: Install the new fuel pump into the assembly. If replacing the fuel filter, do so now.
6. Reinstall the Fuel Pump Assembly: Carefully reinstall the fuel pump assembly into the fuel tank, ensuring a proper seal.
7. Reconnect Fuel Lines and Electrical Connectors: Reconnect the fuel lines and electrical connectors, ensuring they are securely attached. Double-check your work against your photos or the repair manual.
8. Raise the Fuel Tank: Carefully raise the fuel tank back into place and re-secure it with the tank straps.
9. Reconnect the Battery: Reconnect the negative battery terminal.
10. Prime the Fuel System: You may need to crank the engine several times (with the ignition switch ON, not cranking) to prime the fuel system before it will start.
Important Considerations:
* Fuel Pressure: If you have a fuel pressure gauge, check the fuel pressure after installation to ensure it's within the manufacturer's specifications.
* Repair Manual: This is crucial. The steps above are a general guideline. A repair manual specific to your 1991 Camaro RS will provide detailed instructions and diagrams, vital for successful completion.
* Safety: Work in a well-ventilated area away from open flames. Gasoline is highly flammable and potentially explosive.
This is a complex repair. If you're uncomfortable performing this task, it's best to take your car to a qualified mechanic. Improperly replacing the fuel pump can lead to significant damage to your vehicle or even injury.
