Fuel tank replacement
First, work in a clean, organised area. Clutter can cause accidents. If working indoors, ensure there are no pilot lights or other sources of flame or sparks present. Keep the area well-ventilated and have a fire extinguisher on hand. Make sure you have the necessary tools and equipment for the task, including fasteners, clamps, and connections that must be removed or loosened to access the fuel tank.
Second, drain the fuel from the tank. Many tanks have a small stop valve that allows you to drain the fuel neatly. Simply loosen the valve and let the fuel run into a fuel can. If your car does not have a fuel tank valve, remove one of the fuel lines and use it to drain the tank. There should be two fuel lines: a smaller line at the bottom of the tank that directs fuel to the engine, and a larger line at the top used for filling the tank. Detach all lines from the old tank.
Third, remove the old fuel tank. Depending on the model, you may need to drop the rear suspension. If so, support the assembly with a floor jack and remove the lower shock mount bolts. Then, disconnect the rear brake lines and remove the large nuts attaching the rear beam or drive assembly to the frame of the car. Lower the assembly to the ground using the jack. Remove the fuel tank straps by loosening the nuts at one end of the straps and pulling them down.
Fourth, install the new fuel tank. Place the new tank into position and attach it using the same straps as the old tank. Go through the removal steps in reverse to ensure the lines are in place. Fill the car with the appropriate fuel and inspect the tank for any drips or leaks.
Finally, some recommended fuel tank brands for the Ford Focus include Carquest Premium, Delphi, and Dorman. These brands offer reliable and durable fuel tanks that meet or exceed OEM specifications.

Opening the fuel door
The process for opening the fuel door of a Ford Focus depends on the model year. For some models, you can simply pull the fuel door open. Other models have a spring-loaded release, which requires you to gently press inward on one side of the door. There is no interior button.
To open the gas tank on newer Ford vehicles, depress the door until the release latch pops open and the door swings freely. For some models, you will need to gently press the fuel door inward, while for others, you can simply open the door outward.
If the fuel filler door fails to open, you can use the manual override lever. This lever is located in the luggage compartment on the right side behind a panel. To access it, follow these steps:
- Shift your vehicle into park (P) and switch the ignition on.
- Remove the panel located in the luggage compartment on the right side.
- Locate and pull the manual fuel filler door release lever.
- Switch the ignition off and refuel your vehicle within 20 minutes. If more time is needed, close the fuel filler door and repeat the procedure.
Note that before refueling, you must press the fuel filler door release button on the instrument panel to unlock the fuel tank refueling valve and open the fuel filler door. It can take up to 15 seconds for the door to open.

Fuel type
The fuel type for a Ford Focus depends on the model year. The 2020 Ford Focus, for example, requires regular unleaded 87 octane gasoline. The fuel economy is up to 23 MPG in the city and 34 MPG on the highway.
Some Ford Focus owners have reported using mid-grade 89 octane fuel, such as Shell or Mobil, and filling up with ethanol-free fuel when it is available. Others have used 87 octane fuel from brands like Citco, Sunoco, Mobil, and Citgo. Using 87 octane fuel from Union 76 and Chevron did not provide the same performance.
If your Ford Focus is flex-fuel capable, you can use E-85 fuel. This fuel has a higher octane rating, which can provide a boost in power. However, E-85 burns hotter, resulting in slightly lower gas mileage.
In Europe, unleaded fuel with 94 or 95 octane is commonly available. Several fuel companies, including Shell, BP, and Opet, offer fuels with claimed power and mileage-increasing additives.

Fuel tank removal
To remove the fuel tank from a Ford Focus, there are a number of steps to follow. Firstly, it is a good idea to use up as much of the gasoline as possible before you prepare to remove the tank. Disconnect the filler pipe and vent hose by loosening the hose clamp—be careful not to use sharp tools on the clamp, as this could damage the pipe. Disconnect the charcoal canister at the rear of the tank by pulling off the vapor hoses and releasing the fitting. Depress the metal clip and lift the canister.
Next, disconnect the supply and return lines from the fuel filter by releasing their fittings. Place a container under the filter to catch any fuel that spills. Disconnect the fuel pump electrical connector and the fuel tank pressure sensor electrical connector. Siphon out the remaining gasoline into a gas can using a vacuum pump-based siphoning kit.
Now, block the front wheels as a safety precaution, then raise the car's rear end and remove the rear wheels. Raise a jack with a block of wood to support the tank, then unhook the tank's straps by removing the strap bolt. Lower the tank and disconnect all other lines, including the wiring plug at the top for the fuel pump and gauge sender. Finally, turn the fuel module to release it from the bottom of the tank.
It is important to note that highly flammable vapors are always present and may ignite, so do not smoke or carry any open flames when working on or near fuel-related components.
