This is a complex task that may require seeking professional assistance.

It is important to note that gasoline is extremely flammable, so extra precautions must be taken when working on any part of the fuel system. Always take the necessary safety measures, such as working in a well-ventilated area and avoiding open flames or sparks.

Fuel filters need to be replaced every 30,000 miles or 30 months

The fuel filter in a 2004 Chevy Silverado is a lifetime fuel filter built into the fuel pump module inside the tank, so it is not replaceable. However, this does not mean that it cannot get clogged up.

Fuel filters are important because they prevent contaminants from getting inside the engine, which could lead to a loss in performance and potential damage to the cylinder lining. They are located in the line leading from the fuel tank to the engine.

While some car manufacturers recommend periodic replacement of the fuel filter, others don't list it as a regular maintenance item. For example, Volkswagen recommends replacing the fuel filter every 20,000 miles, Subaru every 60,000 miles, and Mercedes-Benz every 150,000 miles or 15 years. Older cars may need their filters replaced as often as every two years and 30,000 miles, while newer vehicles can go as long as 50,000 or even 60,000 miles.

If the fuel filter is not replaced, it can get clogged up with dirt and debris over time, which will stop the optimal fuel flow and allow dirt particles to reach the fuel injector. This can lead to engine failure because the fuel pump has to work extra hard to overcome the dirt-clogged fuel filter.

Some signs that your fuel filter needs to be replaced include decreased engine power when driving uphill or towing heavy objects, rough starts when firing up the engine, and sluggish acceleration or hesitation whenever you press the gas pedal.

The fuel system is under constant pressure, so relieve the pressure before disconnecting any fuel lines

The fuel system in your 2004 Chevy Silverado is under constant pressure, so it is important to relieve the pressure before disconnecting any fuel lines. This is a crucial step to ensure your safety and prevent any accidental spills or leaks. Here are some detailed instructions to guide you through the process:

• Prepare the Vehicle: Park your Chevy Silverado on a level surface and engage the parking brake. The engine should be turned off, and you should allow it to cool down if it has been running recently. Ensure you have a Class B type fire extinguisher nearby as an essential safety precaution when working on the fuel system.
• Relieve Fuel System Pressure: Refer to Chapter 4 of your Haynes manual for step-by-step instructions specific to your vehicle. This process will vary depending on your Chevy Silverado's model and configuration.
• Secure the Vehicle on Jack Stands: After relieving the fuel system pressure, raise the vehicle and securely support it on jack stands. This step is necessary for accessing the fuel filter and fuel lines safely.
• Locate the Fuel Filter: The fuel filter is mounted to the right frame rail, near the fuel tank. Before proceeding, use compressed air or carburetor cleaner to clean any dirt or debris around the fuel inlet and outlet line fittings.
• Prepare for Fuel Spills: Have spare rags or a small container ready to catch or wipe up any extra gasoline that may spill from the filter assembly during the disconnection process.
• Loosen the Fittings: There are screw-in fittings at each end of the fuel filter. Using two wrenches, carefully begin to loosen each fitting. One wrench can be used to steady the hex on the filter, while the other wrench unscrews the fuel line nut. This technique will help avoid rounding off the corners of the fuel line nuts.
• Disconnect the Fuel Lines: Once the fittings are loose, separate the fuel lines from the filter. You may now proceed with removing and replacing the fuel filter.

Remember to work cautiously and refer to your Chevy Silverado's repair manual for detailed instructions specific to your vehicle's configuration. Relieving the fuel system pressure is a vital step to ensure your safety and prevent fuel leaks or spills.
