You should NOT attempt this unless you have experience working on cars, are comfortable with fuel system safety procedures, and have the right tools. Improper handling of fuel lines and fuel can be extremely dangerous.
Here's a general outline of the process, but it's not a comprehensive guide and should not be considered a substitute for a proper repair manual specific to your 1993 Corvette:
1. Safety First: Disconnect the negative battery terminal. Work in a well-ventilated area away from any ignition sources. Consider using safety glasses and gloves. Have a fire extinguisher nearby.
2. Drain the Fuel Tank: This is crucial to minimize the amount of fuel you'll be working with. You'll need a suitable container and siphon or pump.
3. Vehicle Preparation: Raise the vehicle securely on jack stands. You'll likely need to remove some underbody panels for access to the fuel tank. Consult your repair manual for specific instructions.
4. Fuel Tank Removal: This involves disconnecting fuel lines, electrical connections (fuel pump), and the tank straps. Extreme caution is needed here. Fuel lines will be under pressure, even after draining, so you may need to relieve this pressure carefully before disconnecting. Refer to a repair manual for the exact procedures for this.
5. Fuel Pump Access: Once the tank is dropped, you'll need to access the fuel pump assembly, which typically houses the fuel filter.
6. Fuel Filter Replacement: This usually involves removing the pump assembly, separating the filter, and installing a new one. Pay close attention to the orientation of the filter and any seals or O-rings.
7. Reassembly: Carefully reverse the steps of removal, ensuring all connections are secure and leak-free. Reconnect the fuel lines and electrical connections. Double-check all connections before lowering the fuel tank.
8. Priming the Fuel System: After reassembly, you'll likely need to prime the fuel system to ensure the engine starts. This may involve turning the ignition key on and off several times or using a specific priming procedure. Consult your repair manual.
9. Check for Leaks: After starting the car, carefully inspect all fuel connections for leaks.
I strongly recommend obtaining a repair manual specific to your 1993 Chevy Corvette. This manual will provide detailed instructions, diagrams, and torque specifications, crucial for safely and correctly completing this repair. A Haynes or Chilton manual is a good place to start. If you're not comfortable performing this repair, take your Corvette to a qualified mechanic. This is not a job for a beginner.
