VW Fuel Pump Assembly - Genuine VW 3C8919051A

Product Information

A fuel pump module assembly is a complete unit, typically located inside the fuel tank, that delivers pressurized fuel to the engine. Unlike a standalone fuel pump, the module will sometimes include:

• Electric fuel pump – draws and pressurizes fuel.
• Fuel filter/strainer – removes debris and contaminants.
• Fuel pressure regulator – maintains consistent fuel pressure.
• Fuel level sending unit – communicates fuel level to the gauge.

Key functions:

• Supplies pressurized fuel to the injectors for combustion.
• Maintains proper fuel pressure under different driving conditions.
• Provides accurate fuel level readings to the dashboard gauge.

• Engine stalling or no-start condition – pump fails to deliver fuel.
• Loss of power or hesitation – weak fuel pressure causes poor acceleration.
• Hard starting – requires long cranking before the engine runs.

About Genuine VW

The Volkswagen Group, also known as “VAG”, consists of Volkswagen, Audi, Lamborghini, Bentley, Bugatti, Porsche, Ducati, MAN, Scania, SEAT, and Skoda. The original parts used by VW to build your car are available as replacement parts under the “Genuine VW” brand. Manufactured under the direction of VW, expect excellent quality and a premium price since these parts are available exclusively through the VW Dealership network.

You may not realize this, but the parts that make up your VW are not necessarily manufactured by VW. No cause for concern, as VW designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for VW for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine VW parts box and find an OEM branded part inside, simply with the addition of a VW logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming directly from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
