Replacing the fuel pump in a Scion iQ is a complex process that requires careful attention to detail. The procedure involves removing the fuel pump supply and return hoses, EVAP system hoses, and electrical connections to the pump. In some cases, it may be necessary to drain the fuel tank or even lower the fuel tank from the vehicle to gain access to the pump. Once the pump is removed, reusable brackets and pick-up screens are transferred to the new pump before installation. This process can be time-consuming and may require specialised tools and knowledge, so it is recommended that vehicle owners consult a qualified technician for assistance.

What You'll Learn
Removing the fuel tank
To replace the fuel pump in a Scion IQ, you will need to remove the fuel tank. This is a large job that may involve draining the coolant and oil, removing many engine components, and replacing the intake manifold gasket.
First, relieve the pressure within the fuel rail by briefly running the engine with the fuel pump fuse out. Then, remove the fuel pump supply and return hoses, as well as EVAP system hoses, and electrical connections to the pump.
The fuel pump is then removed from the tank through an access panel above the tank in the passenger compartment. If there is no access panel, the fuel must 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 out, any reusable brackets and pick-up screens are attached to the new pump, then the new pump is installed.

Disconnecting the fuel and electrical connectors
To disconnect the fuel and electrical connectors of a Scion IQ, you will need to relieve the pressure within the fuel rail by briefly running the engine with the fuel pump fuse out. Once the engine is cold, you can then disconnect the fuel and electrical connectors.
If there is an access panel above the tank in the passenger compartment, you can remove the fuel pump through this. If there is no access panel, you will need to drain the fuel from the tank and then lower the fuel tank from the vehicle to gain access to the pump.
Once the pump is out, you will need to remove the fuel pump supply and return hoses, as well as EVAP system hoses, and electrical connections to the pump.
It is recommended that you disconnect the battery prior to accessing the fuel pump.

Removing the supply and return hoses
To remove the supply and return hoses, you will need to access the fuel pump. In some vehicles, this can be done through an access panel above the tank in the passenger compartment. If there is no access panel, the fuel must be drained from the tank and then the fuel tank must be lowered from the vehicle to gain access to the pump.
Once you have access to the pump, you can begin to remove the supply and return hoses. First, disconnect the battery. Then, unbolt the pump from the fuel tank and disconnect it from the fuel and electrical connectors.
Next, you can focus on the supply and return hoses specifically. These hoses will be connected to the pump, so you will need to carefully detach them. Make sure to also remove any EVAP system hoses and electrical connections to the pump.
Once the pump is out, you can set it aside and focus on preparing the new pump for installation. Any reusable brackets and pick-up screens can be attached to the new pump.
Finally, you can install the new pump by reversing the removal process. Connect the new pump to the fuel and electrical connectors, bolt it into place, and then reconnect the battery.

Testing the new pump
Prior to testing, it is important to disconnect the battery to ensure safety. Once the new fuel pump is inserted, you can begin the testing process.
Firstly, compare the movement of the old fuel pump to the new one. Adjust the arm if there is any discrepancy in the movement to ensure an accurate fuel level display on the gauge.
Next, check the fuel pump supply and return hoses, EVAP system hoses, and electrical connections to the pump. Ensure that all hoses and connections are properly secured and intact.
If the new fuel pump was installed due to a whirring or humming noise from the fuel tank, test the vehicle to ensure the noise has ceased. This noise often indicates an imminent failure of the fuel pump, so it is important to confirm that the new pump has resolved the issue.
Finally, take the vehicle for a test drive to ensure the new fuel pump is functioning optimally. Listen for any unusual noises and pay attention to the vehicle's performance to ensure a smooth and efficient drive.
By following these steps, you can confidently test and verify the proper functioning of the new fuel pump in your Scion iQ.

Reattaching reusable brackets and pick up screens
To replace the fuel pump in a Scion IQ, you must first remove the fuel pump supply and return hoses, as well as EVAP system hoses, and electrical connections to the pump. Once the pump is out, any reusable brackets and pick-up screens are attached to the new pump.
The new pump is then inserted, connected, and tested prior to reassembly of the vehicle. It is recommended that the movement of the old fuel level sending unit is compared to the new one. If one moves farther in either direction, the arm should be adjusted to ensure the proper level will display on the gauge.
In some vehicles, the fuel tank must be removed to access the fuel sending unit. The sending unit and fuel pump are unbolted from the fuel tank and disconnected from the fuel and electrical connectors. The battery is disconnected prior to accessing the fuel pump.
If there is a whirring or humming noise coming from the fuel tank area, towards the rear of the car, the fuel pump may be failing. If the noise is coming from the fuel pump, it should be replaced as soon as possible. The fuel pump is tested to be sure it isn't functioning. The fuel pump is removed from the tank through an access panel above the tank in the passenger compartment. If there is no access panel, the fuel is first drained from the tank and then the fuel tank is lowered from the vehicle to gain access to the pump.
