Here's a general outline of the process. Specific steps may vary slightly depending on your exact Camaro's configuration (engine type, etc.):
1. Preparation:
* Safety First: Disconnect the negative battery cable. Work in a well-ventilated area. Fuel is flammable.
* Gather Tools: You'll need jack stands, a jack, various sockets and wrenches (including a fuel line disconnect tool is highly recommended), screwdrivers, a fuel pump retaining ring tool (often a special tool), safety glasses, gloves, rags, and possibly a new fuel filter (it's a good idea to replace it while you're in there).
* Consult a Repair Manual: A Haynes or Chilton repair manual specific to your 1991 Camaro RS is invaluable. It will provide detailed instructions, torque specifications, and diagrams. This is highly recommended.
* Drain the Fuel Tank (Partially): This significantly reduces the amount of fuel you'll be working around and makes the job safer. You can use a siphon pump for this.
2. Accessing the Fuel Pump:
* Lower the Fuel Tank: This is usually the most challenging part. You'll need to:
* Support the fuel tank securely with jack stands.
* Disconnect the fuel lines (carefully!), the fuel sender unit (electrical connector), and the tank straps. A fuel line disconnect tool will be helpful here.
* Carefully lower the tank. You may need to use blocks of wood or other supports to prevent it from hanging too low.
* Locate the Fuel Pump: Once the tank is lowered sufficiently, you'll locate the fuel pump assembly. It's usually accessed through a circular access cover on the top of the tank.
3. Removing and Replacing the Fuel Pump:
* Remove the Access Cover: This may require removing bolts or clips.
* Remove the Fuel Pump Retaining Ring: This is where the special tool usually comes in. It's important to remove this correctly to avoid damaging the tank or pump.
* Remove the Fuel Pump Assembly: Carefully lift the pump assembly out of the tank.
* Transfer Components: If you are re-using any parts from the old pump (such as the sending unit or fuel level sensor), carefully transfer them to the new fuel pump.
* Install the New Fuel Pump Assembly: Make sure to seat it correctly in the tank.
* Reinstall the Retaining Ring: Use the special tool to ensure a secure fit.
* Reinstall the Access Cover: Securely attach the cover.
4. Reassembly:
* Raise the Fuel Tank: Carefully raise the fuel tank back into its position.
* Reconnect Everything: Reconnect the fuel lines, the fuel sender unit, and the tank straps. Double-check all connections!
* Prime the Fuel System: This is often crucial. Consult your repair manual for the correct procedure. This step ensures fuel flows to the engine when you start it.
* Reconnect the Battery: Reconnect the negative battery cable.
5. Testing:
* Start the Engine: Listen for any unusual noises and ensure the engine runs smoothly.
* Check for Leaks: Carefully inspect all connections for any fuel leaks.
Important Considerations:
* Fuel Pressure: Some fuel pumps require a specific fuel pressure; this may involve using a fuel pressure gauge during installation to ensure it's correct.
* Fuel Filter: As mentioned, it's highly recommended to replace the fuel filter while you have the tank down.
* Safety: Gasoline is extremely flammable and potentially explosive. Take all necessary precautions. If you have any doubts, seek professional help.
This is a complex process. Again, refer to a repair manual specific to your 1991 Camaro RS for detailed, illustrated instructions. Trying to work from general descriptions online can lead to mistakes and potential damage. If you lack experience with automotive repair, it's best to have a qualified mechanic perform this repair.
