Audi A4 / A5 / A6 C6 / Q5 Fuel Pump Tank Lock Ring 4F0201375

Product overview

This new fuel pump lock ring secures the fuel pump or sender unit into the top of the fuel tank, sealing it against the tank opening. The listing shows it under reference 4F0201375 for Audi A4, A5, A6 C6 and Q5 models, and also cross-references 8K0919087A, 4F0919051BA and 4F0919087L. A lock ring is commonly replaced when it is corroded, cracked or damaged during pump removal.

Vehicle compatibility

The part listing names the Audi A4, A5, Q5 and A6 C6 as intended applications. However, the listed fitment and attribute data for this item are inconsistent. The fitment rows list the Audi A5 and A5 Convertible RS5, A4 B8 Avant RS4, A8 D4 4.2 FSI and 6.3 W12, and Volkswagen Touareg 4.2 V8 FSI, while the attribute data lists different part numbers (079127025, 079127025AL, 079127025AD) and refers to Peugeot and Citroen.

Because of these conflicts, fitment is unverified and should be confirmed by part number before purchase.
