The Audi fuel line 1J0820721BH system consists mainly of a fuel inlet line and a fuel return line. The inlet pipe is responsible for transferring fuel from the fuel tank to the engine, while the return pipe returns excess fuel to the fuel tank to maintain pressure balance in the fuel system.

The material of Audi fuel line usually has good pressure and corrosion resistance, and can withstand the impact and chemical erosion of high-pressure gasoline. They are well manufactured and the connections are well sealed, which effectively reduces the risk of gasoline leakage.
Installation position and function
In Audi models, the exact position and function of the fuel line varies from model to model. For example, in the Audi A6L, the fuel inlet pipe, which connects the fuel filter to the fuel pump, is usually located in the engine compartment, and the thicker pipe is the fuel inlet pipe.
The return pipe is used to return gasoline from the high-pressure output to ensure the stability and reliability of the fuel system.
