The Acura RSX is said to have a fuel filter that never needs changing. However, if you are experiencing issues with your fuel pump, it may be necessary to replace the fuel filter sock clip. This is a simple maintenance procedure that can be done by following a few steps. Firstly, ensure you are in a well-ventilated area and have a water hose or fire extinguisher ready as you will be dealing with gasoline and gasoline vapors. Disconnect the battery and remove the gas cap to release pressure in the system and prevent gas from flowing out. Then, remove the pump assembly and the retaining clip that holds the old sock filter in place. Once the retaining ring is off, carefully pry the old filter off and replace it with a new one. Finally, secure the new filter with the tiny retaining clip and continue with the reassembly process.

What You'll Learn

Disconnect the battery to avoid sparks
When replacing the fuel sock filter, it is important to disconnect the battery to avoid sparks. This is a safety precaution to prevent accidents while working on the fuel system. Sparks could ignite gasoline vapors, leading to a dangerous situation.
To ensure safety, it is recommended to work in a well-ventilated area, free from any smokers or sources of ignition. It is also advised to have a water hose or a fire extinguisher readily available in case of an emergency. Additionally, it is best to perform this task when the fuel tank is low, as it allows for better visibility and makes it easier to manage the assembly.
Disconnecting the battery is a precautionary measure to eliminate the risk of electrical power near the fuel pump. This helps prevent any accidental activation of the ignition, which could lead to unexpected sparks. By disconnecting the battery, you remove the possibility of electrical power being transmitted to the fuel pump, reducing the chance of sparks occurring.
While some people suggest that disconnecting the battery may not be necessary, especially if there is no key in the ignition and no chance of the ignition turning on, others argue that it is better to be safe than sorry. Some individuals have shared their experiences of being sprayed with fuel due to pressure in the fuel lines, emphasizing the importance of taking precautions.
To relieve pressure in the fuel lines, it is recommended to get the engine running and then pull the relay for the fuel pump. Waiting for the engine to die from a lack of fuel ensures that the pressure is released before proceeding with the fuel sock filter replacement. This additional step further enhances safety and reduces the risk of sparks igniting gasoline vapors.

Remove the gas cap to prevent gas flow
To remove the fuel filter sock clip of an RSX-S, you must first remove the gas cap to prevent gas flow and release pressure in the system. This is an important step as it helps you avoid spilling fuel and vapors from the gas tank.
The gas cap on any car is one of the most important yet least talked about parts of a vehicle. The gas cap has two main functions:
- The first is to prevent gasoline vapor or liquid from escaping from the tank. Gasoline is highly flammable, and without a gas cap, vapors can leak out of the open gas tank, creating an ignition risk. This is especially true if your car is parked in a hot garage or in the summer sun.
- The second function is to maintain constant pressure inside the fuel cell. This pressure is what allows fuel to flow to the fuel pump and eventually power your vehicle.
If you have a locking gas cap that seems stuck, it may have an internal mechanical issue. Try using substantial force to press down and move the cap yourself. If this doesn't work, you may need to bring your vehicle to a shop for assistance.
It is also recommended to perform fuel sock filter maintenance when your tank is nearly empty. This makes it easier to see inside the tank and ensures that you don't spill fuel when removing the gas cap. Once the gas cap is removed, you can continue with the disassembly process, carefully pulling out the pump assembly and removing the retaining clip that holds the old sock filter in place.
