Replacing The Fuel Pump In Your 2000 Gmc Yukon Xl 1500

If you're looking to replace the fuel pump in your 2000 GMC Yukon XL 1500, you've come to the right place. This is a complex process, so it's important to know what you're doing. The fuel pump is an essential component of your vehicle's fuel system, delivering fuel from the tank to the engine. Over time, fuel pumps can fail, causing the engine to stall or not start at all. To prevent this, it's recommended to replace the fuel filter every 30,000 miles. The average cost for a GMC Yukon XL 1500 fuel pump replacement is between $1,098 and $1,253.

Now, let's get into the steps of how to replace the fuel pump in your 2000 GMC Yukon XL 1500.

Disconnect the negative terminal on the battery

Disconnecting the negative terminal on the battery of your 2000 GMC Yukon XL 1500 is a crucial first step when replacing the fuel pump. This is an important safety precaution as it helps prevent any accidental electrical discharge that could cause sparks or even an explosion when working with flammable liquids like fuel. Here is a detailed guide on how to do this:

• Locate the negative terminal on your battery. It is usually marked with a "-" symbol and connected to the negative battery cable.
• Using an 8-millimeter wrench, loosen the nut that secures the negative battery cable to the terminal. Turn the wrench in a counter-clockwise direction to loosen the connection.
• Once the nut is loose, carefully slide the cable off the terminal. Be sure to wear protective gloves to avoid any potential electrical shocks.
• Move the cable away from the battery to ensure it does not accidentally come into contact with the terminal. You can use a cable tie or clamp to secure it in place if needed.
• If there is a cover over the battery, use an 8-millimeter bolt to remove it. This will give you better access to the battery and terminal.
• With the negative terminal exposed, you can now begin the process of replacing the fuel pump. Just be sure to keep the battery disconnected until you have completed the fuel pump replacement and are ready to start the vehicle.

Remember, safety should always be your top priority when working on your vehicle, especially when dealing with electrical systems and flammable liquids. Take your time, use the proper tools, and follow established safety procedures to ensure a successful and incident-free fuel pump replacement.

Remove the cover and fuel line cap

To remove the cover and fuel line cap of your 2000 GMC Yukon XL 1500, first disconnect the negative terminal on the battery using an 8-millimeter wrench. Next, take off the cover, which is normally secured by an 8-millimeter bolt. Pull off the cover from the fuel line—this is the little cap.

Now, take a rag and a straight-blade screwdriver. Push on the fuel line cap with the screwdriver, but use the rag so that the fuel doesn't spray everywhere. This will relieve the pressure in the fuel system. Put the cap back on.

At this point, you can take the fuel line off. Simply squeeze the connector and twist it back and forth to remove it.

Disconnect the fuel line

Disconnecting the fuel line on your 2000 GMC Yukon XL 1500 is a relatively straightforward process, but it's important to take the necessary precautions and follow the correct steps to ensure a safe and successful procedure. Here's a detailed guide on how to do it:

Step 1: Relieve the Fuel Pressure

Before you begin, it's crucial to relieve the fuel pressure in the system. Start by disconnecting the negative terminal on the battery using an 8-millimeter wrench. Remove any covers on the fuel line and use a rag and a straight-blade screwdriver to push in the release valve. This will release any built-up pressure. Remember to put the cap back on when you're done.

Step 2: Remove the Fuel Line

Locate the fuel line at the back of the tank. Use your fingers, pliers, or a pick tool to squeeze and twist the connector to remove it. There may be a little fuel left in the line, so be prepared to catch any spills with a rag.

Step 3: Disconnect the Vent Canister Connector

Just above the fuel line, you'll find the vent canister connector. You can disconnect this in the same way as the fuel line by squeezing and twisting it off.

Step 4: Remove the Filler Neck Hose

Use an 8-millimeter socket or a straight-blade screwdriver to loosen the filler neck hose. You may need to use a pick tool to get underneath and twist it to loosen it completely. In some cases, you may need to lower the tank slightly to access it fully.

Step 5: Lower the Fuel Tank

To access the fuel pump and associated lines, you'll need to lower the fuel tank. Use a transmission jack with a special adapter for fuel tanks to support the tank while you work. Remove the bolts securing the fuel tank straps with a 15-millimeter socket, being careful not to use an impact gun as it can damage the nuts. Once the bolts are removed, slide the straps down and out of the way.

Step 6: Disconnect the Fuel Lines and Electrical Connectors

With the tank lowered, you can now disconnect the fuel lines and electrical connectors. First, disconnect the e-EVAP vapor line by pushing on the tabs. Then, locate the fuel pressure line, which goes over the crossmember. Remove the clip securing it and use a rag to wrap around the connector before disconnecting it to avoid any fuel spray.

Step 7: Lower the Tank Completely

Now that the fuel lines and electrical connectors are disconnected, you can lower the tank completely. Be sure to clean the top of the tank with a blowgun or similar tool to remove any dirt and debris.

By following these steps, you'll be able to successfully disconnect the fuel line on your 2000 GMC Yukon XL 1500, making it ready for further maintenance or repairs. Remember always to exercise caution when working with fuel lines and to have a bucket and rags nearby to catch any spilled fuel.

Remove the filler neck hose

To remove the filler neck hose, you will need to relieve the fuel system pressure and disconnect the negative battery cable. Once this is done, drain as much fuel as possible from the fuel tank. Disconnect the filler fuel hose and the electrical connection to the old pump.

Next, support the fuel tank using a jack stand and a block of wood. Remove the entire pump assembly, including the pump and the fuel level sending unit, and lower the tank.

Now, you can remove every hose clamp, disconnect the fuel line or fuel tank hose, and extract the original pump from the gas tank.

It is important to note that dealing with gasoline can be dangerous, so it is recommended to hire a professional mechanic to replace the fuel pump.

Lower the fuel tank

To lower the fuel tank, you will need to disconnect the lines at the front of the tank. First, disconnect the e-EVAP vapour line by pushing on the two tabs to disconnect the connector. Next, disconnect the fuel pressure line. This can be found by feeling at the back of the cross member. You will need to remove the clip that holds the line in place. Wrap a rag around the line and disconnect it to avoid spraying fuel everywhere.

Now you can start to lower the tank. Tip the tank down at the back and then back the tank up a little. Slide the tank back a little and lower it down. Before you go any further, disconnect the electrical connectors. There will be two of these. Now you can lower the tank all the way.

Blow off any dirt and debris from the top of the tank. Take off the connectors by pushing on the two sides of the lock tab and sliding it up. There will be some fuel, so use a rag to wipe it off.
