Fuel Supply Line / Fuel Pipe – 4G0201220

Original pressurized fuel line (semi-rigid supply line for the injection system with SAE quick-release couplings), designed for Audi A7 Sportback (4K / 4K8 generation) and Audi A6 C8 (4K2 / 4K5 / 4KA type) models produced from 2018 to 2026, equipped with a turbocharged 3.0 V6 TFSI (55 TFSI trade designation, DLZA / DKMB engine code) mild hybrid (MHEV 48V) unit, based on the modular longitudinal MLBevo platform.

Original VAG fuel supply system component. Made of multi-layer, gasoline- and biofuel-resistant polyamide (PA) material with reduced vapor permeability, combined with a reinforced flexible hose that dampens drive unit vibrations. It is responsible for the safe, leak-proof, and lossless transport of fuel under low pressure from the tank / in-tank pump directly to the engine compartment section and high-pressure fuel pump (HPFP), ensuring stable pressure in the supply system and full fire safety.

Fitment guarantee and VIN verification

Every fuel line undergoes a thorough body leak test, inspection of the internal seals in the snap-fit sockets, and cleaning before shipping.

Fitment / installation tip: Catalog group 201 refers to tank and fuel line components. In new-generation 3.0 TFSI engines, flexible plastic lines operate under elevated temperatures in the engine compartment. Worn, cracked, or leaking quick-release couplings pose a direct risk of gasoline leaking onto the heated engine block or catalytic converters. The original OEM line guarantees factory seal integrity of the couplings and a perfect fit for the factory guide clips on the longitudinal beam and bulkhead wall. Before purchase, we recommend comparing the OE number on the line label or verifying fitment using the vehicle's VIN.
