Product Overview

The high pressure fuel pump, OEM number 03C127026D, is fitted across the Volkswagen Group's 1.2 TSI and 1.4 TSI/TFSI engine family, covering models including the VW Golf, Polo, Jetta, Tiguan, and Eos, the Audi A1, A3, and S3, Skoda vehicles including the Golf-platform Yeti, and the Seat Ibiza, Leon, and Toledo. Because this pump spans such a wide range of shared-platform models across four brands, it's a high-turnover part worth carrying at volume for anyone supplying VAG-group workshops.

Worn units typically show up as engine jitter, hesitation or loss of power under load, difficulty starting, or a check engine light related to fuel pressure. GSK Auto manufactures this fuel pump to OEM specification at our Ningbo, China facility, with every unit tested before packing. We supply at wholesale volume with low MOQ and support private label packaging, with our team available to confirm fitment before shipping.

Confirm against your VIN or chassis code before ordering - this pump has a long list of letter-suffix variants (C through Q) across model years and engine codes, so it's worth double-checking the exact suffix your customer needs.

What Is a High Pressure Fuel Pump?

• Function: The high pressure fuel pump pressurizes fuel from the low-pressure lift pump to the pressure required for direct injection, delivering it to the fuel rail and injectors.
• Working Principle: Driven mechanically off the camshaft, the pump uses a plunger to compress fuel to high pressure, with an internal control valve regulating output based on engine demand.
• Importance: On a direct-injection TSI/TFSI engine, precise fuel pressure is essential for combustion timing and efficiency, so a failing pump directly affects how the engine runs, starts, and performs under load.
• Common Failures & Signs: Worn internal components causing inconsistent fuel pressure. Engine jitter or rough running, especially under load. Hard or extended cranking before starting. Reduced power output or a check engine light tied to fuel pressure codes.
