How to Clean a Sedan Fuel Tank?

[LeLukas]

The method for cleaning a sedan fuel tank is as follows: 1. Clean and inspect the exterior of the fuel tank, check for dents and leaks in the tank, fuel pipes, and joints, and tighten the fuel tank bracket mounting bolts; 2. Open the fuel tank cap, remove the filter screen, and siphon out part of the fuel from the tank, leaving about 30L of fuel inside. Insert a cleaned compressed air pipe into the tank through the fuel filler opening to reach the bottom, and use air pressure to agitate the fuel at the bottom of the tank for cleaning. If the drained fuel appears dirty, repeat the cleaning process as described above. After cleaning, add clean fuel to the tank, secure the tank cap, and wipe the exterior of the tank clean. Finally, note that the fuel drained from the tank must be allowed to settle for 72 hours before it can be used.
