Replacing Fuel Pump In 01 Saburban: Step-By-Step Guide

Replacing the fuel pump on a 2001 Chevrolet Suburban can be a complex task. The fuel pump is located in the vehicle's gas tank, and access to it often requires lowering the tank from the vehicle. However, some models may have an access panel above the tank in the passenger compartment, which can make the process easier. Before beginning the replacement, it is important to drain the fuel from the tank to avoid spills. Once the tank is accessible, the fuel pump supply and return hoses, EVAP system hoses, and electrical connections must be disconnected. When installing the new pump, it is crucial to ensure that all hoses and electrical connections are properly re-established and that any reusable brackets and pick-up screens are attached. Additionally, it is recommended to replace the fuel filter and check the fuel tank straps and fasteners for excessive corrosion.

Unbolt filler neck top

To unbolt the filler neck top of your 2001 Chevrolet Suburban, you will first need to locate the filler neck. This is usually found near the fuel tank, attached to the fuel filler hose. Once you have located the filler neck, you will need to gather the appropriate tools, such as a wrench or socket set, to unbolt it.

Before you begin, it is important to ensure that you are working in a well-ventilated area, as you will be working with fuel lines, and to place a suitable container underneath the filler neck to catch any fuel that may spill during the process. It is also recommended that you wear safety goggles and gloves to protect your eyes and hands.

Now, follow these steps:

• Place the container underneath the filler neck to catch any spilled fuel.
• Locate the bolts that secure the filler neck to the fuel filler hose or the vehicle's frame.
• Using the appropriate tool, loosen and remove the bolts. You may need to use a wrench or socket set, depending on the type of bolts securing the filler neck.
• Once all the bolts are removed, carefully lift or wiggle the filler neck to detach it from the fuel filler hose or the frame.
• Set the filler neck aside in a safe place, as you will need to access it later when installing the new one.

Remember to be cautious when performing these steps, as you are working with fuel lines, and ensure that you have adequate ventilation and have taken the necessary safety precautions.

Look for a ground wire

When looking for the ground wire, you will need to refer to the wiring schematic for your vehicle. The ground wire is shared with the fuel pump relay and is usually located at the left front of the engine block.

The ground wire is typically black and white and is only 6-7 inches long. You will need to trace the wire to find the ground, which is often located on the left front of the engine compartment. The engine block is several feet from the fuel pump.

If you are having trouble locating the ground wire, you can splice a longer wire to the ground, which will allow you to reach an ideal ground spot.

It is important to ensure that the ground wire is securely connected to a clean, rust-free area. A loose connection can generate heat and disrupt the voltage supply, causing the pump to malfunction.

Undo fuel hose with blue tabs

To undo the fuel hose with blue tabs on a 2001 Chevrolet Suburban, follow these steps:

First, locate the fuel hose. It will be connected to the fuel pump, which is located in the vehicle's fuel tank. Once you have located the fuel hose, look for the blue tabs. These tabs are usually used to secure the connection between the fuel hose and the fuel pump. Using a pair of pliers or a similar tool, gently pry or pull on the blue tabs to release the fuel hose from the fuel pump. Be careful not to apply too much force, as you do not want to damage the tabs or the hose itself.

Once the tabs are released, you can carefully pull the fuel hose away from the fuel pump. Again, be gentle and take your time to avoid any damage to the hose or the surrounding components. It is also important to note that gasoline may still be present in the hose, so use caution and have a suitable container or rag ready to catch any spills or drips.

If the hose is difficult to remove, you may need to apply some gentle force or wiggle the hose slightly to loosen it from the pump. Once the hose is removed, set it aside in a safe place, away from any potential ignition sources. Remember to also disconnect any electrical connections and remove the fuel pump tool before attempting to remove the fuel pump itself.

By carefully following these steps, you can safely and effectively undo the fuel hose with blue tabs on your 2001 Chevrolet Suburban during the fuel pump replacement process.

Undo electric connections

To undo the electrical connections when replacing the fuel pump on a 2001 Chevrolet Suburban, follow these steps:

Firstly, locate the electrical connector for the fuel pump. This is usually a white plastic connector with an orange tab on the side. Spray some WD-40 or PB Blaster into the connector to help loosen any corrosion or buildup that may be present.

Next, identify the orange tab on the side of the connector. This tab has grooves and can be slid or squeezed to release the connector. Carefully slide or squeeze the orange tab and then try to pull the connector apart. If the orange tab breaks, don't worry, you can still release the connector by pushing in at the bottom of the white tab below the orange tab. This will release the top of the connector, allowing you to pull it apart.

If the connector is still stuck, try prying gently with a small tool, such as a pick, to release the wire clip inside the connector. You can also try a new connector if you're having trouble with the old one.

Once the electrical connector is released, you can proceed to replace the fuel pump. Make sure to handle the wiring harness carefully to avoid any damage to the old or brittle plastic components.

Re-establish all hoses and electrical connections

Once you have the new fuel pump in place, it's time to re-establish all the hoses and electrical connections.

First, re-attach the fuel pump supply and return hoses, as well as the EVAP system hoses. Make sure all hose clamps are securely tightened.

Next, reconnect the electrical connections to the pump. If there is a ground wire, make sure it is properly connected.

If there is a new way to redo the harness, do so. Ensure that the ring is back in its original position, or you may need to drop the tank again.

Finally, add fuel to the tank and run the engine to test for leaks.
