What You'll Learn
Removing the fuel pump
To remove the fuel pump from your 2006 Prius, you will first need to test the fuel pump to be sure it isn't functioning. If the pump is faulty, it can be removed from the tank through an access panel above the tank in the passenger compartment. If there is no access panel, the fuel will need to be drained from the tank and then the fuel tank must be lowered from the vehicle to gain access to the pump.
Once the pump is outside the tank, the mechanic will disconnect the fuel lines, remove the pump and install the new one. If the fuel pump supply and return hoses, as well as EVAP system hoses, and electrical connections to the pump are removed, then the pump is out.
Before replacing the pump, the mechanic will power the fuel pump directly to confirm that the issue is a failed pump versus a faulty power supply to the pump. If the fuel filter was replaced recently, whenever the fuel pump is replaced a new fuel filter should be installed.
Once the pump is replaced, another check will be done to ensure there are no fuel leaks and that the problem is solved.

Replacing the fuel filter
Once it has been established that the fuel pump is faulty, the next step is to remove it from the tank. This can be done through an access panel above the tank in the passenger compartment. If there is no access panel, the fuel will need to be drained from the tank, and the fuel tank will need to be lowered from the vehicle to gain access to the pump.
With the cover off, the fuel pump supply and return hoses, as well as EVAP system hoses, and electrical connections to the pump must be removed. Any reusable brackets and pick-up screens can then be attached to the new pump before it is installed. It is recommended that whenever the fuel pump is replaced, a new fuel filter should also be installed.
After the new pump is installed, all hoses and electrical connections are re-established, and fuel is added to the tank. The engine is then run to test for leaks, and a final check is done to ensure there are no fuel leaks and that the problem has been solved.

Testing the fuel pump
If the fuel pump is indeed faulty, it will need to be removed from the tank. This can be done through an access panel above the tank in the passenger compartment. However, if no access panel exists, the fuel must first be drained from the tank, and then the tank must be lowered from the vehicle to access the pump.
Once the pump is outside the tank, the mechanic will disconnect the fuel lines and remove the pump. Any reusable brackets and pick-up screens are then attached to the new pump before installation. It is recommended to replace the fuel filter during this process unless it has been replaced recently.
After installing the new pump, the mechanic will add fuel to the tank and run the engine to test for leaks. This step ensures that the problem has been resolved and that the vehicle is safe to drive.

Checking for fuel leaks
Yes, you can replace the fuel pump in your 2006 Prius. However, it is recommended that you get a professional mechanic to do this for you.
If you suspect a fuel leak, it is important to get it checked out as soon as possible. Fuel leaks can be extremely dangerous, and may lead to fire or an explosion.
If you notice a leak underneath the rear of the vehicle, or smell gasoline, you should take your car to a mechanic. They will inspect the ground underneath the gas tank to see if gasoline has pooled, and then inspect the tank itself to identify the source of the leak. They will then determine whether the tank can be repaired or needs to be replaced.
If the tank needs to be replaced, the mechanic will drain the old tank, disconnect the original fuel lines, and remove the straps that hold the tank in place. They will then install a new tank, ensuring that all the appropriate parts are reconnected. They will add fuel to the tank and start the vehicle to make sure the fuel system is working properly.
If the leak is coming from the fuel lines, this may require a different repair. Finding the origin of the leak will help determine what repairs need to be made.

Disconnecting the fuel lines
To disconnect the fuel lines, a technician will first need to remove the cover and, in some cases, drain the fuel. This is done to gain access to the pump, which is typically located inside or outside the fuel tank. Once the pump is outside the tank, the technician can proceed to disconnect the fuel lines.
It is important to note that prior to replacing the fuel pump, a mechanic should power it directly to confirm that the issue is indeed a failed pump and not a faulty power supply. Additionally, whenever the fuel pump is replaced, a new fuel filter should be installed as well.
After disconnecting the fuel lines and removing the old pump, the technician will install a new pump, ensuring that any reusable brackets and pick-up screens are attached. They will then reconnect the fuel lines and perform a final check to ensure there are no fuel leaks and that the problem has been resolved.
