The 2009 Infiniti G37x has a built-in fuel filter inside the fuel pump assembly, located within the fuel tank. This filter is designed to last the lifetime of the car and does not require regular cleaning or maintenance. However, some owners have reported sediment buildup around 60,000 miles, even with the use of top-tier fuel and fuel system cleaners. While it is not recommended, if you choose to clean the fuel filter, it can be done by manually cleaning out the screens or replacing parts.

What You'll Learn
The Infiniti G37X fuel filter is built into the fuel pump assembly
The fuel filter is considered a non-serviceable item, designed to last the lifetime of the car. However, some owners have reported sediment buildup around 60,000 miles, even when using top-tier fuel and fuel system cleaners.
If you are experiencing issues such as power loss, engine stalling, decreasing fuel mileage, or engine overheating, it could indicate a failing fuel pump. In such cases, it is recommended to replace the entire fuel pump assembly, as only an exact fit will work for your Infiniti G37X.
While fuel pumps don't require routine servicing, maintaining a full tank can help the pump operate cooler and prolong its lifespan.

It is located inside the fuel tank
The fuel filter on your 2009 Infiniti G37X is located inside the fuel tank. It is built into the fuel pump assembly, and there is no external fuel filter. This means that accessing and cleaning the fuel filter will involve removing the fuel tank and disassembling the fuel pump.
It is important to note that the fuel filter in this vehicle is considered a non-serviceable item, meaning it is designed to last the lifetime of the car and is not intended to be cleaned or replaced. However, if you are experiencing issues with fuel mileage, there are some steps you can take.
First, check the fuel pump and the fuel filter for any signs of dirt or sediment buildup. If the fuel filter is found to be clogged, you may need to replace the entire fuel pump assembly, as per Infiniti's recommendation. This is because the fuel filter is integrated into the fuel pump and cannot be cleaned or replaced separately.
If you decide to replace the fuel pump assembly, it is important to follow the manufacturer's guidelines and seek professional assistance if needed. Additionally, consider using fuel additives or cleaning agents, such as Chevron Techron, to help maintain the fuel system and prevent future issues.
Remember to always refer to your owner's manual for specific information regarding your vehicle's maintenance and service intervals.

It is considered a non-serviceable item
The fuel filter on the Infiniti G37X is considered a non-serviceable item, and it is designed to last the lifetime of the car. This means that it is not necessary to clean or replace the fuel filter during the vehicle's lifespan.
The fuel filter is built into the fuel pump assembly and is located inside the fuel tank. There is no external fuel filter to access and clean. Instead of a traditional fuel filter, there is a fuel sock inside the gas tank, which is not typically accessible for cleaning.
If the fuel filter does become clogged or dirty, it is possible to clean it manually, but this would involve accessing the fuel pump and fuel tank, which is not a standard maintenance procedure. Cleaning additives in the gas are not designed to clean the fuel filter but are used to clean injectors, valves, and other components.
Some Infiniti G37X owners have reported that their fuel filters have become caked with sediment around 60,000 miles, despite using top-tier fuel and fuel system cleaners. However, others have found that their fuel filters remain clean even after 50,000 miles.
While the fuel filter is considered non-serviceable, Infiniti recommends replacing it after 100,000 miles if necessary. This would involve replacing the entire fuel pump assembly, as per the manufacturer's recommendations.

Cleaning additives will not clean the fuel filter
The Infiniti G37, like its predecessor the G35, does not have a fuel filter. Instead, it has a fuel sock in the gas tank. This sock is considered a non-serviceable item, meaning it is designed to last the lifetime of the car and does not require regular cleaning or replacement.
While some fuel additives claim to clean fuel systems, they are not effective in cleaning the fuel sock or fuel filter. Fuel additives are designed to clean injectors, valves, and other components of the fuel system, but they do not have the ability to dissolve dirt or contaminants trapped in the fuel sock or fuel filter.
In some cases, using fuel additives without first cleaning or replacing a dirty fuel sock or filter can be counterproductive. The additives may loosen dirt and contaminants, but these particles will then become trapped in the fuel sock or filter, potentially leading to clogs and reduced performance.
Therefore, if you suspect that your Infiniti G37x's fuel sock is dirty or clogged, the recommended course of action is to replace the fuel sock or manually clean out any screens, rather than relying on fuel additives. Additionally, it is important to follow the recommended maintenance schedule and replace the fuel sock or filter at the specified intervals to ensure optimal fuel system performance.
It is worth noting that some Infiniti G37 owners have reported a drop in fuel mileage, even when the car has relatively low mileage. In such cases, it may be necessary to consult a mechanic or Infiniti dealer to diagnose and address any potential issues with the fuel system, including the fuel sock or filter.

To clean the fuel filter, replace parts or manually clean screens
The Infiniti G37X does not have a traditional fuel filter. Instead, it has a fuel sock or a non-serviceable fuel filter built into the fuel pump assembly, located inside the fuel tank. This means that it is not designed to be cleaned or replaced during the lifetime of the car.
However, if the fuel filter does need to be cleaned, there are two options: replacing parts or manually cleaning screens.
Replacing parts:
- It may be necessary to replace the entire fuel pump assembly, as the fuel filter is built into this assembly.
- It is recommended to replace the fuel pump at the same time as the fuel filter.
Manually cleaning screens:
- This involves physically cleaning the fuel filter by removing any built-up sediment or debris.
- Cleaning additives will not clean the fuel filter, as they are designed to clean injectors, valves, and other components.
It is important to note that attempting to clean or replace the fuel filter may void any warranties or guarantees on the vehicle, and it is recommended to consult a qualified mechanic or the Infiniti G37X owner's manual for specific instructions and safety precautions.
