Replacing Your 2005 Colorado Fuel Filter: Step-By-Step Guide

If you're looking to replace the fuel filter on your 2005 Chevrolet Colorado, you've come to the right place. This is a moderately difficult task that should take an hour or less and cost between $7 and $25 for the fuel filter itself. Before you start, make sure you have the necessary tools, including a jack, jack stands, wheel chalks, and a fuse puller or needle-nose pliers. You'll also want to refer to your Colorado service manual or contact a certified mechanic, as not all GMT355 trucks are the same. Now, let's get started:

First, remove the fuel pump fuse from the fuse box. This is a small 15-amp fuse located between the fuel pump relay and the center mounting bolt. Then, start the truck and let it run until it dies, which should only take a few seconds. Turn off the truck and remove the gas cap to relieve any pressure in the tank.

Next, jack up the truck enough to get underneath the driver's side. You'll want to jack it up about a foot to give yourself room to maneuver. Towards the rear of the cab, you'll see the fuel filter. The inlet (from the tank) is on the left, and the outlet (towards the engine) is on the right.

Now, it's time to remove the fuel lines from the filter. Look for the two little plastic squares on the connectors of the hoses attached to the filter ends. Push those in to remove the lines. It's a good idea to remove the inlet hose first to reduce fuel loss. Have a rag handy, as you will lose some fuel from both the hose and the filter.

If your new filter has plastic clips, remove them—you won't need them. Make sure the filter is installed correctly, with the inlet on the left and the outlet on the right. It should slide into the holding bracket and sit tightly. When reconnecting the lines, make sure you hear a click to ensure each side is locked on tightly.

Finally, lower the truck, put the fuse back in, and screw on the gas cap. Inspect for leaks by turning the ignition to the ON position and letting it sit for a few seconds. Repeat this step twice, and your truck should start right up!

Jacking up the truck

Park your truck on a level surface and engage the parking brake. Gather the necessary tools, including a jack, jack stands, wheel chocks, and a fuse puller or needle-nose pliers. Place the wheel chocks behind the rear wheels to prevent the vehicle from rolling.

Identify the jacking points on the driver's side of the truck. Consult your owner's manual or a repair guide specific to your vehicle model for the exact jacking points. Place the jack at the designated point and slowly raise the vehicle until it is high enough to access the underside of the truck. Ensure the jack is securely positioned and stable before proceeding.

Once the truck is raised, carefully position the jack stands underneath the vehicle, following the manufacturer's recommendations for placement. Lower the vehicle onto the jack stands, ensuring they are securely in place and able to support the weight of the truck.

At this point, you should be able to crawl under the truck and locate the fuel filter. It is typically located towards the rear of the cab on the driver's side. The inlet (from the tank) will be on the left, and the outlet (towards the engine) will be on the right.

Before proceeding with any fuel-related work, it is crucial to relieve the pressure in the fuel system. Open the hood and locate the fuel pump fuse in the fuse box. Remove the fuse, then start the truck and let it run until it dies, which should only take a few seconds due to the leftover gas in the lines. Turn off the truck after it runs out of gas.

Now, you can proceed with the fuel filter replacement. Refer to a repair guide or seek guidance from a certified mechanic if you need further instructions on replacing the fuel filter. Once the new filter is installed, lower the truck, put the fuse back in, and screw on the gas cap.

Remember to inspect for leaks after completing the fuel filter replacement. Turn the ignition to the "ON" position without starting the engine and let it sit for a few seconds. Check for leaks again to ensure a secure connection and no fuel loss.

Removing the fuel pump fuse

To remove the fuel pump fuse from a 2005 Chevrolet Colorado, follow these steps:

First, locate the fuse box. The fuel pump fuse will be a small 15-amp fuse located between the fuel pump relay and the center mounting bolt. It is fuse #13. Remove this fuse from the fuse box.

Next, start the truck and let it run until it dies. This will only take 2-3 seconds, as the truck will be running off the leftover gas in the lines. Turn off the truck after it runs out of gas.

Now, remove the gas cap to relieve any extra pressure in the gas tank.

Then, jack up the truck enough to get underneath the driver's side. You will need to jack it up about 1 foot to have room to maneuver. Towards the rear of the cab, you will see the fuel filter. The inlet (from the tank at the rear) will be on the left, and the outlet (towards the engine) will be on the right.

Look at the connectors on the hoses attached to the filter ends. You will see two small, plastic squares. Push those in to remove the lines from the filter. It is recommended to remove the inlet hose first (the one that comes over the top of the filter), as this will leave the outlet hose connected and reduce fuel loss. Have a rag handy, as you will lose some fuel from both the hose and the filter.

Now that the fuel lines are disconnected, carefully lower the truck, put the fuse back in, and screw the gas cap back on.

Finally, inspect for leaks. Turn the ignition to the 'ON' position with the truck off and let it sit for a few seconds. Inspect for leaks one more time. By priming the fuel line in this way, you will ensure that fuel is in the lines. Repeat this step twice, and your truck will start right up!

Locating the fuel filter

There are some conflicting opinions regarding the fuel filter on certain models and years of the Chevy Colorado. Some sources suggest that there is no replacement fuel filter for certain models, as the fuel pump module in the gas tank has a small suction screen instead. However, other sources mention the presence of an external fuel filter on the Chevy Colorado. It is recommended to consult the owner's manual or reach out to a certified mechanic for accurate information specific to your vehicle.

The fuel filter is positioned in the line leading from the gas tank to the engine and prevents contaminants from getting inside the engine, which could lead to a loss in performance and potential damage to the cylinder lining.

Disconnecting the fuel lines

Step 1: Jack up the truck from the driver's side front. Ensure that the vehicle is tilted backward to allow the fuel to move away from the filter. It is recommended to have less than a quarter tank of gas to reduce the weight and pressure of the fuel in the lines.

Step 2: Remove the 15-amp fuel pump fuse from the fuse box and start the engine. The truck will run for a few seconds on the leftover gas in the lines and then die. Turn off the truck after it runs out of gas.

Step 3: Get under the truck and locate the fuel filter. It is positioned in front of the fuel tank on the driver's side. You will see black fuel lines connected to the filter ends.

Step 4: To disconnect the fuel lines, first, push the fuel line in slightly (about a quarter of an inch) and then press the grey tabs or plastic squares on the backside of the connector. Use your thumb and index finger to press these tabs in. Then, move the line back and away from the filter. Be careful not to pull excessively on the line as it is made of plastic. Have some rags or a drip pan ready to catch any spilled fuel.

Step 5: Repeat the process for the opposite end of the fuel filter. Once both ends are disconnected, gently push the filter towards the driver's side to remove it from its holder. You may need to bend the plastic tabs holding it in place.

Remember to work carefully and refer to your Colorado service manual or seek professional assistance if needed. Ensure you have the necessary tools and safety equipment before beginning any maintenance work.

Installing the new filter

Now that you've relieved the pressure in the gas tank and removed the old filter, it's time to install the new one.

First, check if your new filter has plastic clips. If it does, remove them—you won't be needing them. Next, make sure that the filter is facing the correct way: the inlet should be on the left, and the outlet on the right. Slide the filter into the holding bracket. It should sit nice and tight.

Now, reconnect the fuel lines. You should hear a click when each side locks on tightly. Remember to put the inlet hose back on first to reduce fuel loss.

Once the new filter is in place, you can lower the truck, put the fuse back in, and screw the gas cap back on. Before you start the engine, inspect for leaks. Turn the ignition to the 'on' position and let it sit for a few seconds. Repeat this step twice, and your truck should start right up!
