Here's a general outline. Always consult your specific vehicle's repair manual for detailed instructions and diagrams. The steps may vary slightly depending on the engine (e.g., 5.3L, 4.8L, etc.).
Tools You'll Likely Need:
* Jack and jack stands: Securely support the vehicle.
* Wheel chocks: For added safety.
* Socket set (metric): Various sizes will be needed.
* Wrench set (metric): Especially for fuel lines.
* Fuel pump pliers (or special tool): To disconnect the fuel lines safely. These are highly recommended to avoid damaging the lines.
* Screwdrivers (Phillips and flathead): May be needed for access panels.
* Fuel line disconnect tool: Makes disconnecting fuel lines easier and safer.
* New fuel pump assembly: Make sure you get the correct one for your Suburban's engine.
* Safety glasses and gloves: Protect yourself.
* Torque wrench: To tighten bolts to the manufacturer's specifications.
* Shop rags: To clean up any spills.
* New fuel filter: It's a good idea to replace this while you're in there.
* Drain pan: To catch any spilled fuel.
Steps (General Outline – Refer to your repair manual for specifics):
1. Disconnect the battery: This is crucial for safety. Disconnect the negative (-) terminal first.
2. Lower the fuel tank: This is the most labor-intensive part. You'll likely need to:
* Access the fuel tank from underneath the vehicle.
* Remove the fuel filler neck (may require loosening straps and disconnecting electrical connectors).
* Disconnect fuel lines (use fuel line disconnect tools to prevent leaks). Be prepared for some fuel to spill out; use rags to absorb it.
* Disconnect the fuel pump electrical connector.
* Unbolt the fuel tank straps and carefully lower the tank. You might need to support the tank with a jack or straps as you lower it. Be very cautious as the tank is heavy and contains fuel.
3. Access the fuel pump: The fuel pump is typically located inside the tank. You may need to remove an access panel on top of the tank.
4. Remove the old fuel pump: This usually involves unbolting the pump assembly and disconnecting any remaining wiring or fuel lines.
5. Install the new fuel pump: Carefully install the new fuel pump assembly, ensuring it's correctly seated. Reconnect all fuel lines and electrical connections.
6. Raise the fuel tank: Carefully raise the fuel tank back into its position. Secure it with the straps.
7. Reconnect everything: Reconnect all fuel lines, electrical connectors, and the fuel filler neck.
8. Reconnect the battery: Reconnect the battery positive (+) terminal.
9. Prime the fuel system: You may need to crank the engine several times (with the key) to prime the fuel system before it starts.
10. Check for leaks: Carefully inspect all connections for leaks.
Important Considerations:
* Fuel pressure: Some fuel systems require pressure relief before working on them. Consult your repair manual.
* Professional help: If you are not comfortable performing this repair yourself, it's best to take your Suburban to a qualified mechanic. Improperly handling fuel can be dangerous.
This is a simplified overview. The actual procedure can be more complex and involve additional steps. Always consult your vehicle's repair manual for detailed, step-by-step instructions and safety precautions specific to your 2001 Chevy Suburban. Using a Haynes or Chilton repair manual is strongly recommended.
