OEM fitment with Seal and OEM spec fuel pressure regulator

The fuel pump is located inside the fuel tank. To access it, you will need to remove the seat and detach the fuel tank from the bike. This will involve disconnecting the fuel lines, vent hose, electrical connector, and the fuel tank mounting bolts. Be sure to place a container underneath to catch any spilled fuel.

Once the tank is removed, you can access the fuel pump assembly, which is located at the bottom of the tank. The fuel pump is secured to the assembly with a mounting ring, which you will need to remove to access the pump. Be careful not to damage the rubber gasket that seals the pump to the assembly.

Now, you can remove the old fuel pump and install the new one. Make sure to transfer the rubber gasket from the old pump to the new one, as this is critical for maintaining a proper seal. Also, ensure that the new pump is correctly oriented and seated properly in the assembly. Reinstall the mounting ring, being careful not to overtighten it, as this can damage the gasket.

Finally, you can reinstall the fuel tank and reconnect all the fuel lines, vent hose, and electrical connector. Be sure to check for any leaks before starting the bike.

When replacing the fuel pump, it is recommended to also replace the fuel filter and the fuel pressure regulator. The fuel pressure regulator is responsible for maintaining the correct fuel pressure in the system. It is located on the fuel pump assembly and is connected to the fuel lines. To replace it, simply disconnect the fuel lines and remove the old regulator. Install the new regulator and reconnect the fuel lines, ensuring all connections are secure and leak-free.

The fuel pressure regulator plays a crucial role in ensuring the fuel pump operates within the correct pressure range. It helps maintain the optimal fuel pressure required for the fuel injectors to function properly. By replacing it along with the fuel pump, you can ensure that the entire fuel system is operating at its best, providing the necessary fuel flow and pressure for the engine.

Fuel pump strainer and filter

The fuel pump strainer and filter on a Harley Davidson Sportster 1200 Custom are important components of the fuel system. The strainer and filter work together to ensure that the fuel entering the engine is free of contaminants and debris.

The strainer is like a tea bag that fits onto the bottom of the fuel pump and then folds up the side, secured with zip ties. It is designed to remove coarse particles from the fuel. The filter, on the other hand, is a fine particle filter that further ensures that the fuel is clean before it enters the engine.

When replacing the fuel filter, it is important to also check the condition of the strainer. If the strainer is disintegrating, as some users have reported, it can cause debris to enter the fuel system and potentially cause issues with the fuel pump and engine. Therefore, it is recommended to replace the strainer and filter together as a kit to ensure optimal fuel system performance.

There are replacement fuel pump strainer and filter kits available for the Harley Davidson Sportster 1200, which include both the strainer and the filter. These kits are designed to fit specific Sportster models, so it is important to verify compatibility before purchasing.

• "I installed the first one, what a pain! It constantly squealed louder than my motor. I sent it back for a replacement and the next one is quieter than the OEM one I replaced. It's been in my '01 Road King for over a year now. So don't settle for a noisy one!"
• "Pleasantly surprised. Getting the unit in and out of the tank was difficult but installing the new pump to the existing assembly was easy.. Got over a 100 miles on the new pump. Quiet and works great. I would say it's a good value for the money. Update: now have over 400 miles on this pump. Working great!"
• "Fits and works right now."
• "Just installed on 2000 Road King FLHRCI. Was identical to OEM and runs great after assembly. I didn't need the regulator due to my model (my mistake). I decided to replace when I had to replace my check valves since I had access to the pump with 90,000 miles."
