What You'll Learn
Remove the spark plug wires and the bolts supporting the power hard lines
To remove the spark plug wires and the bolts supporting the power hard lines, you will need to first open the hood of your Subaru. Familiarise yourself with the engine layout. The spark plug wires are crucial for delivering the electrical current from the ignition system to the spark plugs. They are usually connected to the top of the spark plugs.
Before removing the spark plug wires, make sure the area around them is clean and free of debris. Use a cloth or towel to wipe away any dirt or grime that may fall into the engine cylinders during the removal process. Start by carefully disconnecting the spark plug wires from the old spark plugs. To do this, firmly grasp the spark plug wire boot (the rubber part) and gently twist it while pulling it away from the spark plug. Avoid pulling on the wire itself, as this can damage the wire or the connection.
Now, remove the 2 10mm bolts that support the two power hard lines. With the intake out of the way, you will be able to access the cover that hides the leaky fuel line. Remove the 12mm bolt holding the cover to the intake manifold. You will then see 2 12mm bolts that hold the cover in place. Once these are removed, you can take off the cover and set it aside.
It is important to note that there is a hole on the cover that faces the radiator. This opening allows you to tighten the clamp without removing the cover. However, if the previous person who worked on the engine did not turn the screw, you will need to remove the cover to access the fuel line.

Remove the hose in front of the fuel line
To remove the hose in front of the fuel line, you will first need to expose the internal fuse box. Open the tray to the left of the steering wheel and pull up to release the hinge at the bottom of the tray. Remove the 15-amp fuse in the top left corner, which is the fuse for the fuel pump. Try to start the car to relieve the fuel pressure. There will be some fuel that will dribble out.
Next, remove the air intake. There are two 10mm bolts on the front of the intake and one 10mm nut that need to be removed. With the intake out of the way, you will be able to access the cover that hides the leaky fuel line. Remove the spark plug wires from the coil pack on top of the engine and set them aside.
Now, remove the two 10mm bolts that support the two power hard lines, and the 12mm bolt holding the cover to the intake manifold. Look lower on the cover and you will see two 12mm bolts that hold the cover in place. Once these bolts are removed, you can take off the cover and set it aside.
With the cover removed, you will have access to the fuel line. There is a hose in front of the fuel line that slides over a barbed end. Remove this hose to give yourself more room to work and to prevent accidentally poking a hole in it.

Cut the old fuel line
To cut the old fuel line, you will need to first relieve the fuel pressure. This can be done by removing the fuse for the fuel pump, which is located in the internal fuse box to the left of the steering wheel. With the fuse removed, try to start the car to release the pressure. There will be some fuel dribbling out, so be prepared to catch it with a container.
Next, remove the air intake by taking out the two 10mm bolts on the front of the intake and the 10mm nut that secures it in place. Once the intake is out of the way, you will be able to access the cover that hides the leaky fuel line. Remove the spark plug wires from the coil pack on top of the engine and set them aside. Take out the two 10mm bolts that support the power hard lines and the 12mm bolt holding the cover to the intake manifold.
Now, look lower on the cover and you will see two 12mm bolts that hold the cover in place. Remove these bolts and set the cover aside. With the cover removed, you will have access to the fuel line. Before cutting the old fuel line, make sure to remove the hose that is in front of it. This hose simply slides over a barbed end, so gently pull it off. Now, you can cut the old fuel line using a razor or a utility cutter. Be careful not to cut or damage any other components in the engine bay.
It is worth noting that some people choose to tighten the clamp on the fuel line instead of replacing it. This can be done through the hole on the cover that faces the radiator. However, if the fuel line is damaged or severely leaky, it is best to replace it.

Warm the hose to soften it before putting it on
Warming the hose before putting it on is a good idea, especially if you are working in cold weather. This is because the rubber can become stiff and inflexible, and warming it will make it softer and easier to work with. It is important to note that you should only use dry, warm water and not hot water, as this could damage the hose.
One way to warm the hose is to use a hot pack. Place the hot pack on or around the hose until it has softened to your desired level. You can also use sunlight to warm the hose, but be aware that continuous exposure to sunlight and UV rays can cause the hose to degrade over time. If you are going to use this method, only expose the hose to sunlight for the minimum amount of time required to soften it.
Another method to soften the hose is to soak it in warm water. Fully submerge the hose in a container of warm water and leave it to soak until it has softened. You can also add vinegar to the water, as this will help to break down any oxidation that is causing hardness in the rubber. However, if you do use vinegar, be sure to rinse the hose with clean water afterwards.
Additionally, you can periodically apply silicone lubricant to the hose to keep it supple and prevent premature hardening. This will help to maintain and prolong the hose's flexibility.

Remove the fuel rail guard to access the clamps
Removing the fuel rail guard on a 2002 Subaru can be a challenging task due to the design of the car. It is important to gain access to the clamps to ensure that the fuel line is tightened or replaced.
To begin the process of removing the fuel rail guard, it is essential to have the engine cover removed. This will provide access to the bolts holding the guard in place. In most cases, there are two 10mm bolts that need to be loosened. However, it is not uncommon to find only one bolt, as the other may have been forgotten during a previous service. Using a 10mm socket with an extension will provide the necessary leverage to loosen the bolts. It is important to note that the nuts can become stiff due to the heat of the engine, so applying some force may be required.
Once the bolts are loosened, the guard itself may still feel tight. This is expected, especially if it hasn't been removed for a long time. There are no additional clips holding the guard in place, so it should be possible to pull it off after loosening the bolts.
Removing the fuel rail guard is a crucial step in gaining access to the clamps. It is recommended to refer to a Haynes manual for a detailed diagram of the process, which will aid in ensuring that the correct components are being accessed and that the procedure is followed safely.
