If you own a Harley-Davidson motorcycle and you’re experiencing issues with your fuel system, chances are you need to clean or replace your fuel injectors. To access the fuel injectors, you’ll need to remove the fuel tank. This may seem like a daunting task, but with the right tools and a bit of patience, it’s a straightforward process. In this guide, we’ll walk you through the steps to remove and clean your Harley fuel injectors, starting with accessing the fuel injectors by removing the fuel tank.
Removing The Fuel Tank
To access the fuel injectors, you’ll need to remove the fuel tank. Before you begin, make sure your motorcycle is on a level surface and that the fuel tank is empty. Here’s how you can remove the fuel tank:
- Remove the seat by loosening the bolts on the rear fender and lifting the seat off.
- Disconnect the negative cable from the battery using a wrench to loosen the nut.
- Remove the fuel cap and disconnect the fuel line from the tank. Make sure to have a container ready to catch any fuel that may spill out.
- Remove the bolts that secure the fuel tank to the frame using a socket wrench. There are usually two bolts at the front of the tank and one at the rear.
- Lift the fuel tank off the frame and place it in a safe location.
Locating The Fuel Injectors
Now that the fuel tank is removed, you can access the fuel injectors. The fuel injectors are located on the throttle body, which is connected to the intake manifold. The throttle body is typically located on the top of the engine, towards the front of the motorcycle. Once you’ve located the throttle body, you can easily locate the fuel injectors.
To remove the fuel injectors, you’ll need to disconnect the electrical connectors and fuel lines that are attached to them. Make sure to label each connector and fuel line so that you can easily reconnect them later. Once all the connectors and fuel lines have been removed, you can simply pull the fuel injectors out of the throttle body.
In conclusion, accessing the fuel injectors is the first step towards cleaning or replacing them. By following these simple steps, you can easily remove the fuel tank and locate the fuel injectors on your Harley-Davidson motorcycle.

Detaching Fuel Lines And Connectors
To remove the fuel injectors from your Harley, you’ll first need to detach the fuel lines and connectors. This step requires careful attention to ensure a smooth and successful removal process.
Start by locating the fuel lines and connectors attached to the fuel injectors. These are typically located near the intake manifold or fuel rail. Carefully inspect the connectors and identify any retaining clips or tabs that may be securing them in place.
To detach the connectors, gently press or squeeze the tabs while simultaneously pulling the connectors away from the injectors. Take care not to apply excessive force, as this may damage the connectors or the injectors themselves. If the connectors are stubborn, a small flathead screwdriver can be used to assist in releasing them.
Once the connectors are detached, move on to the fuel lines. Depending on the model of your Harley, there may be multiple fuel lines connected to each injector. Begin by identifying the appropriate line for each injector.
Using a line wrench or an adjustable wrench, carefully loosen the fittings connecting the fuel lines to the injectors. Be cautious not to overtighten the wrench, as this can cause damage. Once the fittings are loose, gently twist and pull the lines away from the injectors, ensuring that no fuel spills or leaks occur.
Careful Removal Of Injectors
With the fuel lines and connectors detached, it’s time to proceed with the careful removal of the fuel injectors from your Harley. This step requires precision and attention to detail to avoid any damage to the injectors or surrounding components.
Before attempting to remove the injectors, make sure to clean the surrounding area to prevent any debris from falling into the intake manifold or other sensitive parts. This can be done using a clean cloth or compressed air.
To remove the injectors, gently grasp each one near the base and carefully wiggle and pull them straight out. Avoid twisting or applying excessive force, as this can cause damage to the injectors or their seals.
As you remove each injector, place them in a clean and safe area to prevent any contamination or damage. It’s essential to keep track of the order in which the injectors were removed, as they will need to be reinstalled in the same positions later.
Remember, the removal process should be performed with caution and patience. If you encounter any difficulties or are unsure about any step, it is recommended to consult a professional or refer to your Harley’s service manual for guidance.
