The fuel filter on a Harley-Davidson FXR motorcycle is typically located within the fuel tank. Some models, such as the 1985 Super Glide FXR, feature fuel filters within the fuel petcock, which is a valve that controls the flow of fuel. It is important to regularly check and clean the fuel filter, especially if the motorcycle runs on biofuel or is stored with an incomplete fuel tank, as this can lead to internal corrosion and rusting.

What You'll Learn
The fuel filter is located in the tank
The fuel filter is located inside the fuel tank of a Harley-Davidson FXR. To access the fuel filter, you will need to pull the centre dash console. Underneath, there is a plate held in place by small screws and plastic inserts. These screws are single-use, so you will need to replace them along with the gasket under the plate.
Given the complexity of this process, it is recommended to refer to a service manual. Typically, fuel filters are replaced after 40,000-50,000 miles, but some riders choose to wait longer. However, replacing the filter at 20,000-mile intervals can prevent issues with the fuel pump and engine performance.
As demonstrated by one Harley-Davidson FXR owner, the fuel filter can be challenging to access and may require multiple entries into the tank. This owner experienced fuel flow issues and suspected a problem with the fuel pump. Upon inspecting the tank, they discovered the issue was caused by rust and debris, possibly from the pump door gasket, inside the tank.
Over time, the coating inside the fuel tank of a Harley-Davidson FXR can flake off, leading to rust and debris accumulation. This accumulation can cause fuel flow issues and fuel filter clogging. Therefore, it is essential to regularly clean the tank and fuel lines to prevent such problems.

It's recommended to change the filter at 20k intervals
Although Harley-Davidson does not provide any specific guidelines on how often to change the fuel filter on an FXR, it is recommended to change the filter every 20,000 miles. This is based on the experience of FXR owners, who have noticed that changing the filter at this interval helps to improve the bike's performance and fuel pump health.
One FXR owner shared that they changed their fuel filter at 25,000 miles, and while it didn't appear to be in poor condition, they believed it was a wise precaution to take. Another owner with a 2017 CVO Limited FXR also recommended changing the filter every 20,000 to 25,000 miles. They noticed a significant improvement in pump sound after replacing their filter at 48,000 miles.
Some FXR owners have even suggested that the fuel filter be checked or replaced as frequently as every 30,000 miles. They claim that doing so can help avoid problems like a slowly burning pump and a poorly running motor.
It is worth noting that Harley-Davidson recommends a fuel filter replacement interval of 100,000 miles for their 2017 Sportster model. However, some owners find this interval far too long and choose to replace their filters more frequently.
To ensure optimal performance and prolong the life of your Harley-Davidson FXR, it is recommended to adhere to the suggested maintenance intervals, including fuel filter replacement at 20,000-mile intervals. This proactive approach can help prevent issues and maintain the health of your motorcycle.

The fuel filter can be accessed by pulling the centre dash console
The fuel filter on a Harley-Davidson motorcycle is located inside the tank. To access the fuel filter, you will need to pull the centre dash console. This will expose a plate underneath, which is secured by a number of small screws and plastic inserts. It is important to note that these screws are single-use, so you will need to replace them if you need to re-secure the plate.
When accessing the fuel filter, it is recommended to also replace the gasket under the plate. This process can be intricate, so it is advised to refer to a service manual for a Harley-Davidson motorcycle. Additionally, it is worth noting that most people do not typically change the fuel filter until the motorcycle has reached 40,000 to 50,000 miles. However, changing the filter at 20,000-mile intervals can help prevent potential issues with the fuel pump and engine performance.
In the case of the FXR model, there have been reports of issues with fuel filters. One owner of an FXR experienced a problem where their motorcycle appeared to be running out of gas, and they discovered that the coating inside the tank had flaked off. This issue turned out to be related to the fuel filter, as there was a problem with the fuel pump not being seated correctly.
By pulling the centre dash console and accessing the fuel filter, you can perform maintenance or replacement as needed. This process can help ensure the optimal performance of your Harley-Davidson FXR motorcycle and address any potential issues related to the fuel system.

The FXR model is known to have issues with fuel filter flakes
The Harley-Davidson FXR model is known to have issues with fuel filter flakes. While the FXR model is generally well-regarded for its performance and handling, some owners have reported problems with fuel delivery, which can be caused by clogged or blocked fuel filters.
One common issue with the FXR fuel system is debris from the fuel line breaking down and clogging the petcock screen, located inside the fuel tank. This can cause the bike to stall as if it's out of gas, even when there is fuel in the tank. To address this issue, it is recommended to drain the tank, remove the petcock, and check the screen for any large flakes or debris that may be blocking it. It is also advised to replace the fuel line to prevent further issues. These are relatively easy and inexpensive maintenance tasks that can help ensure the smooth operation of the motorcycle.
Some FXR owners have also reported problems with internal corrosion in the fuel tank due to condensation, which can occur if the bike is stored outdoors. This corrosion can cause tank lining to flake off and block the petcock screen, leading to fuel delivery issues. Regularly checking and cleaning the petcock screen can help prevent this problem. Additionally, ensuring proper ventilation by checking for a "whooshing" sound when removing the gas cap can help prevent air leaks that may impact fuel flow.
While some FXR owners have recommended removing the fuel filter entirely, it is essential to consult a professional mechanic or service manual before making any modifications to your motorcycle. Overall, while the FXR model may require some routine maintenance and attention to fuel system components, these issues can typically be addressed through regular checks and relatively simple repairs.

A clogged fuel filter may cause the bike to act like it's running out of gas
Fuel filters are important for the fuel system as they ensure that clean fuel reaches the engine. Over time, contaminants such as sand, dirt, rust, and other debris can mix with gasoline varnish that collects in the fuel tank, clogging the filter and preventing it from performing effectively. This can lead to restricted fuel flow, which can hinder engine performance and cause unnecessary wear and premature failure of other components such as fuel pumps.
It is recommended to replace the fuel filter regularly, with the frequency depending on the quality of gas used and the amount of time riding the bike. Some riders choose to replace the fuel filter every time the oil and air filter is changed, while others wait until it poses a problem. However, it is important to note that ignoring a faulty fuel filter can lead to more severe engine issues and costly repairs.
While some fuel filters can be visually inspected for discoloration, others may be housed within a cartridge, requiring disconnecting from the system to check for airflow obstruction. It is also recommended to check the manufacturer's service interval hours for guidance on fuel filter replacement.
Additionally, installing a Twin Air Fuel Filter can provide an additional layer of protection if your bike frequently experiences clogged filters or if it does not have a regular fuel filter attached to the gas line. This type of filter fits securely under the gas cap and is easy to install and remove.
