Here's a general outline. Consult a 1984 Corvette repair manual for detailed instructions and diagrams specific to your vehicle. These instructions are for general guidance only and may not cover every variation or specific detail.
Safety First:
* Disconnect the battery negative terminal before starting any work.
* Work in a well-ventilated area. Gasoline fumes are highly flammable and potentially lethal.
* Use proper safety glasses and gloves.
* Have a fire extinguisher readily available.
Tools You'll Likely Need:
* Socket set (metric)
* Wrenches (metric)
* Fuel line disconnect tools
* Screwdrivers (Phillips and flathead)
* Jack and jack stands
* Fuel pump pliers (for clamping fuel lines)
* Torque wrench
* Shop rags
* Safety glasses
* Gloves
* Fuel line disconnect tools
* Possibly a fuel pressure gauge
Steps (General Outline):
1. Preparation: Consult your repair manual for the exact location of the fuel pump. On many 1984 Corvettes, it's located in the fuel tank. This means dropping the tank.
2. Lower the Fuel Tank: This is the most challenging part. You'll need to disconnect the fuel lines, the fuel tank straps, and the fuel tank sending unit. Be extremely careful with the fuel lines; spillage is to be avoided. You may need to relieve fuel tank pressure before disconnecting any lines. This is usually accomplished by starting the engine and letting it run until it dies. Consult your manual.
3. Accessing the Fuel Pump: Once the tank is lowered, you'll locate the fuel pump assembly. It is typically attached to the sending unit.
4. Disconnect Electrical Connections: Carefully disconnect the electrical connectors to the fuel pump. Take pictures or make notes to ensure correct reassembly.
5. Remove the Fuel Pump: The process of removing the pump varies depending on the specific design. It may involve removing retaining clips, bolts, or a retaining ring.
6. Install the New Fuel Pump: Install the new fuel pump, ensuring it's correctly seated and aligned.
7. Reconnect Electrical Connections: Carefully reconnect the electrical connectors.
8. Reconnect Fuel Lines: Reconnect the fuel lines, using fuel line clamps to secure them. Double-check all connections for leaks.
9. Raise the Fuel Tank: Carefully raise the fuel tank back into its position and secure it with the straps.
10. Reconnect the Fuel Sender: Reconnect the fuel sending unit.
11. Reconnect Battery: Reconnect the battery's negative terminal.
12. Check for Leaks: Carefully inspect all connections for leaks before starting the engine.
13. Start the Engine: Start the engine and check for proper fuel pressure and operation.
Important Considerations:
* Fuel Pressure: You may need to check fuel pressure after installation to ensure the new pump is functioning correctly.
* Fuel Tank Pressure: If your car uses a vented fuel system, you will want to verify it is in proper working order to prevent pressure build up and potential leak damage.
* Repair Manual: A Haynes or Chilton repair manual for your specific year and model Corvette is invaluable for detailed instructions, diagrams, and torque specifications. Don't attempt this without one.
This process involves handling fuel, so extreme caution is necessary. If you are uncomfortable with any part of this process, it's best to have a qualified mechanic perform the repair. Improperly working on your fuel system can lead to fire, injury, or damage to your vehicle.
