Remove the rear seat cushion of the FAW Audi A6L 2.0T. Use a small flat-head screwdriver to slowly pry open the inspection hole cover. Take off the inspection hole cover and disconnect the fuel pump cable connector. Remove the fuel pump pipe.
Removing the fuel pump line on an Audi A6 requires special attention to safety due to the high-pressure fuel system, which is prone to leaks. First, I disconnect the negative terminal of the car battery and wait ten minutes to allow the system to power down, preventing sparks from causing hazards. Next, I release the fuel pressure—usually by running the engine for a few minutes before pulling the fuel pump fuse to shut off the engine or loosening the fuel tank cap to relieve pressure. Locate the fuel pump; on most Audi A6 models, it's hidden under the rear seat or in the trunk. Remove the decorative cover to access the fuel line connections. Use a specialized wrench to loosen the fittings during removal—never yank forcefully, as this can deform the pipes or cause leaks. I recommend keeping a drip pan and towels ready. The entire process must be done in a well-ventilated area, with no smoking or open flames. After removal, inspect the lines for aging or cracks. If replacing parts, ensure the new lines match the vehicle's model year. Car repairs demand precision—skipping steps can lead to a cascade of issues later.
I once disassembled the fuel line of my Audi A6 at home for cleaning the fuel system. First, I disconnected the positive and negative terminals of the battery—safety first. Then, I depressurized the system. My usual simple method is to open the hood, locate the test valve on the fuel rail, and use a cloth to press it and release the residual gasoline. Once the pressure is released, it's ready to work. Locate the fuel pump—just lift the plastic cover under the rear seat to see the pipes. The connectors might be a bit tight, but don’t panic; just use a dedicated socket to loosen them slowly to prevent debris from falling into the tank. Take photos to remember the positions during disassembly to avoid incorrect reassembly. I noticed rust spots on the old pipe and promptly replaced it, also cleaning the fuel pump filter screen. The whole process took about an hour but was quite labor-intensive. I recommend wearing old clothes and gloves—fuel odor is hard to wash off. DIY disassembly and reassembly require patience and the right tools. Watching online video tutorials beforehand is a safer bet.
