If you want to remove the fuel line from your 2007 Subaru Impreza, there are a few things you need to keep in mind. First, make sure that it is, in fact, the fuel line that needs to be removed and not the fuel tank, as a leaking fuel tank is a more common issue. If it is the fuel line, you can access it through the access panel above the fuel pump, which is located under the rear seat. Once you've located the fuel line, you'll need to disconnect the hoses and plugs from the top of the tank, making sure to relieve the fuel pressure first. Then, you can remove the bolts securing the straps below the tank and use a jack to lower it and access the rest of the connections. Be sure to label the fuel lines so you can remember where they go when it's time to reconnect them.

What You'll Learn
Disconnect hoses and plugs
To disconnect the hoses and plugs, start by making sure your battery is disconnected and the fuel pressure is relieved. There will be a few wire connections that will need to be unplugged. There are also three fuel lines connected to the tank from the side that will need to be unhooked. Be sure to label them so you remember which goes where.
Next, remove the fuel pump assembly to get inside the tank. Once you get the exhaust and the driveshaft out of the way, you can start disconnecting the hoses and plugs from the top of the tank. There are four bolts that secure the two straps below the tank. Put a jack under the tank and lower it a bit so you can disconnect the components on top of the tank that you couldn't reach otherwise. Then, lower the tank to the ground.
It's recommended that you give yourself a good weekend to remove and install the tank.

Remove bolts securing straps
To remove the bolts securing the straps of the fuel line in a 2007 Subaru Impreza, you will first need to drop the gas tank. This is a simple process that does not require removing the crossmember; simply lower it.
Once the tank is lowered, you will have access to the filler hose, fuel lines, and the two strap bolts. If you are replacing a line, you may not need to fully drop the tank. There is also an access panel above the fuel pump, under the rear seat, which you can use to access the fuel lines without dropping the tank.
However, if you do need to drop the tank to access the fuel lines and strap bolts, be sure to do it carefully and follow the correct procedure to avoid any leaks or damage to your vehicle. Take your time and make sure the area is well-ventilated when working with fuel lines.
When removing the bolts, be sure to have a suitable container to catch any fuel that may leak from the lines. Also, make sure you have the correct tools for the job, such as a wrench or socket that fits the bolts securely. You don't want to strip the heads of the bolts, as this will make them much more difficult to remove.

Unhook fuel lines
To unhook the fuel lines on a 2007 Subaru Impreza, you will need to first depressurize the fuel system. This is an important safety step to avoid any accidents.
Next, you will need to locate the fuel lines and identify any clips, tabs, or connectors holding the lines in place. Some vehicles use spring clips or metal tabs, while others may have quick-disconnect fittings. You can try moving the tool back and forth and twisting the line while pulling to unhook it. Alternatively, you can use a fuel line disconnect tool or set, which is relatively inexpensive and available at most parts stores. These tools are designed to simplify the process of unhooking fuel lines by pushing the tabs up so you can pull out the line. If you don't have access to this tool, you may be able to use screwdrivers or similar tools to carefully pry the tabs up.
Be cautious when working with fuel lines, as they can be delicate and prone to damage. It is recommended to have the necessary tools and knowledge before attempting any repairs or modifications. Always refer to the vehicle's service manual for specific instructions and safety precautions.
Unfortunately, I could not find more detailed information specific to the 2007 Subaru Impreza. However, the above information provides a general guide on unhooking fuel lines, which should be largely similar across different vehicles.

Remove rear differential
To remove the rear differential of a 2007 Subaru Impreza, follow these steps:
Begin by putting the rear end of the car on jack stands and chocking the front tires. Remove the rear tires. Unhook the exhaust from the three rear hangers and let it hang, creating more workspace for axle removal on the driver's side and for unfastening the rear carrier from its lower mount.
Use a 1/2" drive (breaker bar) to first undo the fill plug, and then the drain plug. Drain the differential oil into a catch pan. Remove the long outer lateral link bolt on both sides using a 19mm socket/breaker bar/cheater pipe and a 19mm wrench. Torque to 103ft-lb. If you have aftermarket bushings in your trailing arms, remove the bolt from the rear trailing arm on each side.
Support the ring gear with your hand so that it doesn't smash against the inside of the case. Note the position of the notch in the spacers in relation to the plate. Keep the driver's side and passenger's side parts separate, as the spacers vary in thickness. Pull the differential out, with the ring gear side coming out first.
To remove the ring gear from the differential, use an impact gun to remove the 8-14mm bolts, or put the differential into a vice and use a socket and breaker bar.

Check for leaks
Checking for leaks in your 2007 Subaru Impreza is an important step in fuel line maintenance. Over time, the Subaru fuel system is prone to degradation, and leaks can develop due to temperature fluctuations and the resulting wear and tear on the factory rubber fuel lines.
To check for leaks, begin by inspecting the two lower hoses under the turbo inlet, as these are the most common sources of leaks. Look for signs of brittleness or hardening, which can cause the hoses to crack and leak. If you notice any issues with these hoses, they will need to be replaced.
Next, you can try to visually identify any leaks. This can be challenging, as the fuel lines are often hidden behind other components. However, on a cold day, you may be able to see a small drip on the passenger side of the engine compartment, which is a common issue with Subarus.
Additionally, pay attention to any unusual fuel smells, especially during cold weather. Leaking fuel can seep onto the engine, causing a strong fuel odour. This issue can also result in fumes entering the cabin, leading to headaches and potentially causing accidents.
If you suspect a leak, you will need to remove the intake manifold to access the fuel lines fully. This is a time-intensive project, so be prepared to set aside a few hours for the task. Once the intake manifold is removed, inspect the rubber lines that run under the manifold and near the fuel pressure regulator. These lines are prone to failure and may be the source of the leak.
Finally, consider using tools such as hose remover pliers, fuel line disconnect tools, and a Gates hose cutter to aid in your inspection and any necessary repairs.

Frequently asked questions
First, make sure your battery is disconnected and fuel pressure is relieved. Disconnect the hoses and plugs from the top of the tank. There are four bolts that secure the two straps below the tank. Put a jack under the tank and lower it a bit so you can disconnect the stuff on the top of the tank that was out of reach. Then lower the tank to the ground.
There is an access panel above the fuel pump, under the rear seat. If it is the fuel line, it will be wet by the filler neck area.
You can cut a large hole with an air saw to access the fuel line without removing the tank. However, this may affect the integrity of your car.
Some recommend using clean fuel, water, and acetone in the tank.
