Here's a general overview. This is not a complete, step-by-step guide and should not be used as a substitute for a professional repair manual specific to your 1992 Corvette. Consulting a Haynes or Chilton manual for your specific year and model is crucial.
Steps (general):
1. Safety First: Disconnect the negative battery terminal. Allow the fuel system to depressurize. This may involve running the engine until it stalls, then waiting a few minutes.
2. Access the Fuel Pump: This typically involves dropping the fuel tank. The specifics vary depending on whether you have a standard or optional fuel tank (some 1992 Corvettes had larger capacity tanks). This usually entails:
* Raising the car securely: Use jack stands, never work under a car supported only by a jack.
* Removing the access panel: This often involves removing the rear interior panels or the carpet to access the fuel tank straps and sending unit.
* Disconnecting the fuel lines: Carefully disconnect the fuel lines leading to and from the fuel tank. Use fuel-line clamps and be prepared for some fuel spillage. Have rags and possibly a container ready.
* Disconnecting the electrical connectors: Disconnect the electrical connectors to the fuel pump.
* Lowering the fuel tank: Carefully lower the fuel tank, usually using straps or a special fuel tank lowering tool. This is the most physically demanding part of the job. Support the tank appropriately to prevent damage.
3. Replacing the Fuel Pump:
* Accessing the pump: The fuel pump is usually located inside the fuel tank's sending unit. You'll need to remove the sending unit to access the pump.
* Removing the old pump: Carefully remove the old fuel pump from the sending unit assembly. Take note of how everything is assembled, take pictures, etc. You'll need to put the new one back exactly the same.
* Installing the new pump: Install the new fuel pump, ensuring it's seated correctly.
4. Reassembly:
* Reinstall the sending unit: Carefully reinstall the sending unit into the fuel tank.
* Reconnect the fuel lines and electrical connectors: Double-check all connections.
* Raise the fuel tank: Carefully raise the fuel tank back into place.
* Reconnect access panels: Reinstall any access panels or interior components you removed.
5. Testing: Reconnect the negative battery terminal. Turn the ignition key to the "on" position (don't crank) to hear the pump prime. Start the car and check for leaks. Let the car run for a while to ensure proper operation.
Important Considerations:
* Fuel pump pressure: You might need a fuel pressure gauge to verify the proper pressure after installation.
* Fuel tank straps: These can be brittle and break, so be careful when removing and installing them.
* Safety: Always work in a well-ventilated area, wear appropriate safety glasses, and have a fire extinguisher nearby. Gasoline is highly flammable.
* Professional Help: If you're not comfortable with any aspect of this process, it's best to take your Corvette to a qualified mechanic. This is not a job for beginners.
This overview provides a general idea of the process. Consult a repair manual specific to your 1992 Corvette for detailed instructions and diagrams. Failing to follow proper procedures can result in damage to your vehicle or even injury.
