How to Change the Fuel Filter on a 2001 Blazer

The fuel filter is an important part of the fuel delivery system.

Maintaining your fuel system will help keep your 2001 Chevrolet Blazer in good condition. The fuel filter is an important part of the fuel system, cleaning the fuel before it flows into your fuel injector. Over time, the fuel filter will begin to clog, causing dirty fuel to flow into your engine. To prevent this from happening, you should change your fuel filter with every tune-up.

Things You'll Need

• New fuel filter
• Adjustable wrench
• Gloves
• Protective eye wear

Instructions

1. Park your Chevrolet Blazer on level ground in a safe area. Apply the parking brake so the vehicle does not roll while you are working on it.

2. Open the hood of your vehicle. Locate the power distribution box beside the battery. Disconnect the fuel pump relay from the power distribution box. Start the engine, and allow your car to idle until it runs out of gas.

3. Crawl underneath your Chevrolet Blazer from the passenger's side. Locate the fuel delivery system just below the passenger's seat. The fuel filter is mounted to the chassis of the fuel delivery system just in front of the fuel tank and looks like an elongated black or silver container with a black tube at each end. The black tube is your fuel line.

4. Apply pressure to the quick connect fittings that attach the fuel filter to the fuel line. This will reveal a clamp bolt that also connects the fuel filter to the fuel line. Use an adjustable wrench to remove the clamp bolt, disconnecting the fuel filter from the fuel line. Use an adjustable wrench to remove the mounting bolts attaching the fuel filter to the chassis. Remove the old fuel filter and set it aside.

5. Install the new fuel filter, making sure the directional arrow on the filter points toward the front of your vehicle. Secure the fuel filter to the chassis using an adjustable wrench and the mounting bolts. Attach the fuel filter to the fuel line using an adjustable wrench and the clamp bolts. Reconnect the quick connect fittings over the area where the fuel filter and the fuel line come together.

6. Crawl out from underneath your Chevrolet Blazer, and reconnect the fuel pump relay to the power distributor box.
