Changing the fuel pump is a significant job and is NOT recommended for someone without mechanical experience. It involves:
1. Safety Precautions: This is crucial. Disconnect the negative battery terminal BEFORE starting any work. Fuel is highly flammable, so work in a well-ventilated area and avoid sparks or open flames. Gasoline vapors are also dangerous to inhale.
2. Lowering the Fuel Tank: This usually requires removing the fuel tank straps, disconnecting the fuel lines and electrical connectors, and possibly dropping the exhaust system (depending on the specific Corvette model). This requires jack stands and safety measures to avoid injury.
3. Accessing the Fuel Pump: Once the tank is lowered or partially lowered (depending on design), you'll have access to the fuel pump assembly at the top of the tank. There is usually a retaining ring to remove to access it.
4. Disconnecting the Electrical Connections and Fuel Lines: Carefully disconnect the electrical connectors and fuel lines from the fuel pump module. Note how everything is connected. You may have to relieve pressure in the fuel lines.
5. Removing the Fuel Pump Assembly: This often involves removing the retaining ring and carefully lifting the entire assembly out of the tank.
6. Installing the New Fuel Pump: Install the new fuel pump assembly, ensuring that the gasket seals correctly.
7. Re-assemble: Carefully reattach all the fuel lines, electrical connectors, and the fuel tank.
8. Bleed the Fuel System: After reassembly, you'll likely need to bleed the fuel system to remove any air pockets. This may involve turning the key to the "on" position repeatedly (without starting the engine) to prime the pump.
9. Check for Leaks: Carefully check for any fuel leaks after the reinstallation.
Tools You Will Likely Need:
* Jack and jack stands
* Fuel line disconnect tools
* Socket wrench set
* Wrenches
* Screwdrivers
* Safety glasses
* Gloves
* New fuel pump and filter assembly (make sure it's the correct one for your 1998 Corvette)
* Possibly a fuel pressure gauge (to check for proper pressure after installation)
Recommendation: This is a complex repair that should only be attempted by someone with significant mechanical experience and the right tools. Incorrect installation could lead to serious injury or damage to your vehicle. It's strongly recommended to take your Corvette to a qualified mechanic to have this repair performed. They have the experience, tools, and safety precautions in place to do this safely and correctly.
