2H0919050D Fuel Pump - Online wholesale prices

The 2H0919050D is a fuel pump used in various Volkswagen and Audi models. Fuel pumps are critical components of a vehicle's fuel delivery system, ensuring that fuel is efficiently supplied from the fuel tank to the engine for combustion. The 2H0919050D is specifically designed to work with certain engines, particularly in the Audi and Volkswagen lineup, providing reliable fuel pressure for optimal engine performance.

Key Features:

• Function: The primary role of the fuel pump is to deliver fuel from the fuel tank to the engine's fuel injectors. It ensures that fuel is supplied at the correct pressure, which is crucial for the proper operation of the engine and maintaining fuel efficiency.
• Type: Typically, this part is an in-tank fuel pump, meaning it's housed inside the fuel tank itself. This design helps reduce noise and ensures the pump is properly cooled and lubricated by the fuel it pumps.
• Material: Made of durable materials designed to withstand the harsh conditions inside the fuel tank, such as high temperatures and exposure to chemicals in fuel.
• Fuel Pressure Regulation: The fuel pump maintains constant fuel pressure to the fuel injectors, ensuring consistent engine performance. Variations in fuel pressure can lead to poor engine performance, stalling, or difficulty starting.
• Built-in Strainer or Filter: Often comes with a filter or strainer that helps to remove debris and impurities from the fuel before it enters the engine, ensuring that the pump and fuel injectors remain free of contaminants.
• Electric Motor: The pump is typically powered by an electric motor, which is activated when the ignition is turned on. The motor is responsible for driving the internal mechanism that moves the fuel.

Compatibility:

The 2H0919050D fuel pump is compatible with various Volkswagen and Audi vehicles, especially those with fuel systems requiring a high-performance electric in-tank pump. Specific model compatibility may include vehicles with FSi or TDi engines, but it's important to verify compatibility based on the vehicle's make, model, and year.

Importance:

A well-functioning fuel pump is essential for ensuring that the engine receives the correct amount of fuel at the right pressure. Failure of the fuel pump can lead to engine stalling, difficulty starting the car, or no-start conditions altogether. It can also cause poor fuel efficiency, hesitation during acceleration, or a drop in overall engine performance.

When replacing or servicing the fuel pump, it's essential to ensure that the fuel tank is drained and properly ventilated to avoid any risk of fire or injury. Additionally, the fuel pump should be replaced if there are signs of wear, such as strange noises (whining), loss of pressure, or irregular fuel delivery.
