Daysyore Electric Fuel Pump for Johnson/Evinrude Outboards — 200–300 HP, 3.3L & 3.4L (5006063 / 5010821)

Description

High-quality Use

This Johnson Evinrude fuel pump belongs to the electric type. Therefore, it provides powers depending on an electric motor, which is typically a brushed DC motor that is designed to operate on a 12 volt electrical system. Furthermore, the outer electric plug of the high pressure fuel pump is likely there for ease of installation and maintenance. It allows for the pump to be easily connected and disconnected without having to remove other components, such as the fuel line.

Detailed Structure

The diaphragm is responsible for pumping fuel through the assembly, while the inlet and outlet valves control the flow of fuel in and out of the assembly. The fuel level sender is an electronic sensor that is integrated into the fuel pump, it is designed to measure the level of fuel in the tank and send a signal to the fuel gauge on the dashboard of the boat. The strainer is a filter that is located on the inlet side, preventing debris and contaminants from entering the fuel system and damaging the fuel pump or the engine.

Maintenance Tips

• Replace the fuel filter: The fuel filter helps remove contaminants from the fuel before it enters the fuel pump. Over time, the filter can become clogged, which can put additional strain on the fuel pump. It is recommended to replace the fuel filter every 30,000 to 40,000 miles.
• Use high-quality fuel: Low-quality fuel can contain contaminants that can damage the fuel pump. It is important to use high-quality fuel from a reputable gas station to help protect the fuel system.
• Avoid running the fuel level too low: Running the fuel level too low can cause the fuel pump to overheat and work harder, which can reduce its lifespan. It is recommended to keep the fuel level above a quarter tank to help prevent damage to the fuel pump.

• Regularly inspect the fuel system: Inspecting the fuel system, including the fuel lines and connections, can help identify potential problems before they become more serious.
• Check for leaks: Fuel leaks can damage the fuel pump and other components in the fuel system. It is important to check for leaks and have them repaired as soon as possible.
• Have the fuel pump inspected: Regularly having the fuel pump inspected by a qualified mechanic can help identify potential problems before they become more serious.

How to Replace

1. Disconnect the fuel pump relay and allow the engine to run until it stalls to ensure that the vehicle is properly supported and that the fuel system is depressurized.
2. Locate the fuel pump inside or outside the tank, and remove the old fuel pump.
3. Fill the new fuel pump with fuel, and then install it.
4. Tightly and securely connect fuel lines to the new fuel pump.
5. Connect the fuel pump to the vehicle’s wiring harness or to a separate electrical supply.
6. Test the fuel pump. Turn the ignition key to the “on” position and listen for the fuel pump to prime. Check the fuel pressure using a fuel pressure gauge.
7. Reinstall components that were removed during the installation process.
