Replacing Fuel Pump In Scion Xb: Step-By-Step Guide

Replacing the fuel pump in a 2005 Scion xB is a relatively straightforward process that can be completed by a DIY enthusiast or a professional mechanic. The fuel pump is located inside the gas tank, and accessing it requires removing the backseat and unbolting the access panel. It is recommended to refer to a service manual for a safe replacement procedure. While some universal fuel pumps may fit the Scion xB, it is important to ensure that the correct pump is purchased to avoid compatibility issues. Additionally, paying attention to the fuel evaporation tube and its connection to the fuel pump assembly can make the process easier.

The fuel pump is located in the gas tank

To change the fuel pump in a 2005 Scion xB, you'll need to access the pump, which is located inside the gas tank. Here's a step-by-step guide to help you with the process:

Step 1: Accessing the Fuel Pump

Start by locating the fuel pump access panel. In the 2005 Scion xB, this is usually found in the trunk or rear cargo area, under the rear seat. Remove the rear seat cushion by locating and releasing the retaining clips or bolts that hold it in place. Be careful not to damage the seat or its coverings during this process. Once the seat is removed, you should see the fuel pump access panel, typically secured with several bolts.

Step 2: Removing the Access Panel

Use the appropriate tool, such as a socket wrench or a 10mm wrench, to remove the bolts holding the access panel in place. Carefully lift the panel away, exposing the fuel pump assembly. You will now have access to the fuel pump and the sending unit.

Step 3: Disconnecting the Fuel Pump

Before you can remove the fuel pump, you need to disconnect it from the sending unit and unclip the wiring harness. The sending unit is the component that houses the fuel pump and the fuel level sensor. Carefully unclip the wiring harness and set it aside, ensuring that it doesn't fall back into the tank.

Step 4: Removing the Fuel Pump

At this point, you should be able to lift the fuel pump out of the sending unit. It may be necessary to gently wiggle the pump to release it from the unit. Be cautious not to damage any components during this process. Once the fuel pump is removed, you can install the new pump by following these steps in reverse.

Step 5: Reinstalling the Fuel Pump

When installing the new fuel pump, ensure that all connections are secure and that the wiring harness is correctly clipped into place. Reattach the sending unit and secure it with the appropriate clips or bolts. Reinstall the fuel pump access panel and tighten the bolts securely. Finally, carefully reposition the rear seat cushion and secure it with the retaining clips or bolts.

It is important to note that working on fuel system components can be dangerous, so it is always best to exercise caution and refer to a repair manual or seek professional assistance if you are unsure about any part of the process.

You can buy a universal fuel pump for as little as $50

If you're looking to replace the fuel pump in your 2005 Scion xB, you can save some money by opting for a universal fuel pump. Universal fuel pumps are a cost-effective alternative to vehicle-specific pumps, and they can be purchased for as little as $50.

Universal fuel pumps, such as those available from online retailers like Amazon and AutoZone, can be a great option for those on a budget. They typically come with all the necessary clips, bushings, and other installation hardware, making them a convenient choice for DIY enthusiasts. However, it's important to note that not all universal pumps are created equal, and some may require minor modifications or adaptations to fit your specific vehicle.

When purchasing a universal fuel pump, it's essential to consider the quality and reliability of the product. While some universal pumps may be perfectly adequate, others may be made from lower-quality materials or lack the durability of OEM (Original Equipment Manufacturer) parts. To ensure a reliable and long-lasting fuel pump, it's worth investing in a pump with a good warranty and purchasing from a reputable source.

In terms of installation, replacing the fuel pump in a 2005 Scion xB is generally considered a straightforward task. According to online forums, the process typically involves removing the backseat, accessing the fuel pump through an access panel, and then unclipping the old pump before installing the new one. However, it's important to refer to a reliable service manual or seek professional assistance if you're unsure about any steps.

By opting for a universal fuel pump and performing the replacement yourself, you can save a significant amount of money compared to dealership prices. However, always exercise caution when working with fuel systems, and ensure you have the necessary tools and knowledge to complete the job safely and effectively.

You can access the fuel pump by removing the bottom of the back seat and the access panel

To access the fuel pump in a 2005 Scion xB, you'll need to remove the bottom portion of the back seat and the access panel. This process is relatively straightforward and can be completed with some basic tools and careful manoeuvring.

Start by removing the bottom of the back seat. This will expose the area where the fuel pump is located. You'll see two clips holding the seat bottom in place. Simply unfasten these clips to release the seat bottom, allowing you to lift it out of the way and access the underlying components.

With the back seat bottom removed, you'll have better access to the fuel pump assembly. Locate the access panel, which is secured with bolts. Using a 10mm wrench, carefully loosen and remove these bolts. Once the bolts are removed, you can gently pull out the sending unit, which is part of the fuel pump assembly.

At this point, you'll be able to access the fuel pump itself. It's important to work carefully in this area to avoid any damage to the surrounding components and fuel lines. You'll need to unclip the sending unit and carefully detach the harness from the fuel pump. This will allow you to fully expose the fuel pump for inspection, repair, or replacement.

When you're finished working on the fuel pump, remember to carefully reconnect the harness and secure the sending unit back into place. Reinstall the access panel by tightening the bolts with your wrench. Finally, reattach the bottom of the back seat by clipping it firmly into place.

By following these steps, you'll be able to access the fuel pump in your 2005 Scion xB for maintenance or replacement while ensuring that everything is securely reassembled.

The fuel evaporation tube can be tricky to remove

• According to the service manual, simply squeeze the tabs by hand and pull the tube off at the same time. However, this can be challenging to do simultaneously.
• Use a pair of needle-nose vice grips to depress the tabs and standard pliers to pull the tube from the plastic housing.
• There are various screwdriver tricks that can be employed. One method involves using two screwdrivers to gently pry the tube off.
• Leave the bolts around the round metal plate holding the pump in the floor. Spray the fitting with a lubricant like liquid wrench. Use vice grips to carefully depress the tabs (be careful not to apply too much pressure), and use a long socket wrench extension with a rag on one end to gently tap the other end with a hammer until the tube comes off.
