Removing the fuel line from a Subaru Forester can be a tricky task. While some people opt for a siphon pump to remove old gas from their tank, others choose to replace the fuel filter. The process can vary depending on the model year of the Subaru Forester and it is important to take safety precautions to avoid any hazards. This process may be easier on certain model years, such as the 2011 Subaru Forester, which has quick connects for the return line. In this case, a Company23 Fuel Line Disconnect tool can be used to remove the fuel lines.

What You'll Learn
Warming the hose with a hot pack can soften it before removal
When removing a fuel line, it is important to consider the safety and practicality of using old hoses, as replacement is often the best option. This is because old hoses may have lost their flexibility, which can lead to damage during disassembly or assembly. To prevent this, you can try warming the hose with a hot pack to soften it before removal.
One technique for restoring the flexibility of an old rubber hose is to use hot water or warm air. This can help prevent damage during the removal process. However, it is important to note that heating the hose directly next to the fuel tank may not be safe. Instead, consider using warm air from a safe distance to soften the rubber.
Another method for softening rubber hoses is to apply kerosene. Kerosene softens rubber the most, but it can also permanently change the structure of the rubber. This may not be suitable for all vehicles, so it is important to know the specific vehicle model and the cost of replacement parts before attempting this method.
Additionally, you can try using glycerin to soften the rubber. This method is safer than kerosene, but it may not be as effective in restoring flexibility. Soaking the hose in glycerin can help preserve the rubber and make it more flexible.
It is important to prioritize safety when working with fuel lines. If the hose shows signs of cracking or extensive wear, it is best to replace it with a new one rather than attempting to soften it.

Using a lubricant can help when fitting new pieces
Lubrication is an important process that should be considered when fitting new pieces of machinery. It is not a simple process, nor is it optional. Lubrication is critical to a safe working environment and can help extend the service life of components and equipment.
When fitting new pieces of machinery, lubrication can help to reduce friction and heat, thereby reducing wear and tear. This allows equipment and components to remain in an optimal operational state for a longer period of time. By helping to keep components intact and closer to their original form, lubrication can reduce the time between breakdown and replacement, improving overall efficiency and reducing costs.
In the case of a Subaru Forester, proper lubrication can help ensure that the fuel lines remain in good condition and are less likely to become damaged or clogged. This is especially important when dealing with old fuel, which can become stabilized with the addition of fresh gas.
When selecting a lubricant, it is important to consider the nature of the materials being used. For example, mild steel on mild steel has a tendency to seize, which can result in an assembly that does not run true. In this case, heat shrinking the assembly or using a lubricant such as white lead or never-seize may be beneficial.
Overall, using a lubricant when fitting new pieces of machinery can help to improve performance, efficiency, and safety, while also reducing the potential for breakdowns and repairs.

The fuel return line can be used to remove old gas
If you are looking to remove old gas from your Subaru Forester, you can try siphoning the fuel out. This can be done by using a small hose and a pump, or even by mouth in emergencies. You can also try connecting something into the fuel supply quick connector with a clamped hose on the other end.
Another method is to disconnect the fuel line near the frame rail, close to the gas tank. Turn the key in the ignition, but do not start the motor. This action will turn on the fuel pump, which will then dump the fuel through the disconnected line.
If you are unable to remove the old gas using the methods mentioned above, you may need to drop the tank to access the fuel directly. However, this is a more complex process and may require professional assistance.

A siphon pump can be used to remove old gas
Firstly, locate the fuel pump. This can be done by lifting the rear seats and opening the hatch. Once the fuel pump is located, you can siphon the fuel out.
Alternatively, you can disconnect a fuel hose in the engine bay, extend the hose to a bucket or jug, and turn the key to the accessory position. This method will drain the battery, so ensure it is hooked up to a charger or have a spare battery ready. This method will not remove every last bit of fuel, and it is important to not run the pump dry.
It is worth noting that some sources suggest that not all cars use a "return line" to regulate pressure, and that a pump with single output characteristics would result in too much or too little fuel being pumped in low and high-flow situations, respectively. Therefore, it is important to correctly identify the fuel lines before proceeding.
Additionally, modern cars are designed to prevent easy access to fuel in the tank, and some newer vehicles are even siphon-resistant. It is important to exercise caution and refer to the specific make and model of your vehicle for the most accurate information.

The fuel rail protectors can be removed for better access
To remove the fuel rail protectors on a Subaru Forester, first remove the air intake duct, resonator, air filter housing, spark plug wires from cylinders No.1 and No.3, power steering pump, and fuel rail protector. Disconnect the electrical connectors from the fuel injectors and vacuum hose from the fuel pressure regulator. Then, disconnect the fuel supply and return hoses from the fuel rail.
Once the fuel rail protectors are removed, you can then remove the fuel rail and injectors as a single assembly. Remember to replace the old O-rings on each injector with new ones before reinstalling the fuel rail and injectors.
It is important to note that when removing the fuel injectors, you must strictly follow the instructions provided by Subaru to avoid damaging the injectors.

Frequently asked questions
You can use a siphon pump to remove old gas from your 2010 Subaru Forester. You can get a siphon pump for less than $10 USD.
The top one is the fuel supply line, also called the "fuel delivery pipe", and the bottom one is the fuel return line, also called the "evaporation pipe".
The Company23 Fuel Line Disconnect tool is a good option, as it is designed specifically for Subaru fuel quick couplers and will not damage fuel line seals or lines.
Removing the fuel rail protectors is not necessary, but it may provide better access when replacing the fuel lines. You can refer to a Haynes manual for a good diagram of how to remove them.
You can use a Gates 27335 5/16-inch hose with new Amguage 52F15 clamps. Warm the hose with dry, not hot, water to soften it before putting it on.
