Audi D2 A8 Fuel Rail Safety Measure

Last Updated: 12/25/2016
Parts Group: Fuel rail with injectors and fuel pressure regulator
This article discusses the fuel rail for the D2 Audi A8 (1997 through 2002) with the main focus being on depressurizing the fuel rail prior to removing it. If you're not here for the technical analysis but would rather buy a used unit from us, guaranteed to work and fit, then please select the link below.The information herein is based on my own 1998 car.

By removing the fuse to the main fuel pump, while the engine was running, I could starve the fuel system of fuel, and have the fuel pressure in the fuel rail be almost zero. I found the fuse box under the passenger footwell outboard kick panel, and removed the rightmost fuse in the blue section, which is the 4th row, counting from the top.

Sure enough, the engine stopped running. Later, when I removed the fuel lines from the fuel pressure regulator, there was hardly any fuel pressure, which made it a clean and safe procedure.

I also removed the battery from the car, and wrote a note that I taped to the steering wheel with wording such as: "Risk of fire due to open fuel lines. Do not attempt to start this car."
