How do you change fuel pump on 1984 corvette?

Replacing the fuel pump on a 1984 Corvette is a moderately involved job requiring some mechanical aptitude and the right tools. Safety is paramount; disconnect the battery's negative terminal before starting. Gasoline is highly flammable.

Here's a general outline. This is not a comprehensive guide, and you should consult a repair manual specific to your 1984 Corvette. Improper procedures could damage your vehicle or cause injury.

1. Preparation:

* Gather Tools: You'll need jack stands, jack, wrenches (various sizes), sockets, ratchet, screwdrivers (Phillips and flathead), fuel line disconnect tools, safety glasses, gloves, rags, a new fuel pump, and possibly a fuel pressure gauge. A shop manual is highly recommended.

* Safety: Disconnect the negative battery terminal. Allow the fuel system pressure to depressurize (you can do this by cranking the engine a few times after disconnecting the battery – don't crank for extended periods). Work in a well-ventilated area.

* Locate the Fuel Pump: The fuel pump on a 1984 Corvette is typically located in the fuel tank.

2. Accessing the Fuel Tank:

* Lower the Fuel Tank: This usually involves lowering the fuel tank from underneath the vehicle. Consult your repair manual for the specific steps, as this process varies depending on the Corvette's model and options. You'll likely need to disconnect fuel lines, electrical connectors, and possibly the fuel tank's sending unit.

* Support the Tank: Use jack stands and appropriate supports to prevent the tank from falling or shifting during the procedure. Be cautious; fuel tanks can be heavy.

3. Removing the Old Fuel Pump:

* Disconnect Fuel Lines: Use the proper fuel line disconnect tools to safely detach the fuel lines from the fuel pump. Be prepared for a small amount of fuel spillage. Have rags ready to absorb any leaks.

* Disconnect Electrical Connections: Disconnect the electrical connector from the fuel pump.

* Remove the Pump: The fuel pump's mounting method varies, but it usually involves removing bolts or clamps securing it to the fuel tank. Your repair manual will detail this.

4. Installing the New Fuel Pump:

* Install the New Pump: Carefully install the new fuel pump, ensuring it's correctly seated and secured. Follow the instructions that come with your replacement pump and your repair manual.

* Reconnect Electrical Connections: Connect the electrical connector to the new fuel pump.

* Reconnect Fuel Lines: Securely attach the fuel lines to the new fuel pump using the fuel line disconnect tools. Double-check for any leaks.

5. Reassembly:

* Raise the Fuel Tank: Carefully raise the fuel tank back into its original position.

* Reconnect Connections: Reconnect any fuel lines, electrical connectors, and other components that were disconnected.

* Double-Check: Thoroughly check all connections before lowering the vehicle.

6. Post-Installation:

* Reconnect Battery: Reconnect the negative battery terminal.

* Check for Leaks: Inspect all fuel lines and connections for leaks.

* Test the System: Start the vehicle and check for proper fuel pressure (if you have a fuel pressure gauge). Listen for any unusual noises from the fuel pump.
