Daysyore High-Pressure Mechanical Fuel Pump (166307214R) – Compatible with Nissan Qashqai, Dacia Sandero II, Renault Megane IV (2013–2018)

Description

Pressure Conversion

This high pressure fuel pump belongs to a mechanical fuel pump that uses a petrol engine for spark ignition with direct injection systems. It feeds fuel from a low pressure pump in the fuel tank, offers the engine the additional fuel needed to produce more power via camshaft drive, and then discharges fuel at high pressure to fuel injectors, greatly improving fuel delivery.

Optimal Performance

The use of high-quality aluminum and advanced manufacturing techniques ensures that the pump is able to withstand the rigors of daily use and maintains consistent performance over time. Besides, it adopts an engine control unit (ECU) to receive feedback from a built-in pressure sensor or other sensors. This allows the pump to deliver a reliable and constant flow of fuel at the appropriate pressure.

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.
