Although, the fuel tank is fully enclosed except when it is semi-closed when refueling. However, as the truck ages and the use time becomes longer, more and more precipitated impurities in the fuel tank will inevitably enter the engine with the fuel supply system in the truck, which will cause damage to the truck over time. After these impurities enter the truck fuel tank, they first settle on the bottom of the fuel tank. Slowly when there is too much sediment, it will enter the truck’s engine along with the fuel, causing serious wear and tear on the engine.
Generally speaking,fuel tank cleaning is divided into two steps, internal and external. External: check the tank, fuel pipe, joint and other places for dents or fuel leakage. Remember to check whether the fixing screws of the fuel tank bracket are tightened. Internal: Open the fuel tank port, take out the filter barrel, and suck the fuel out, leaving only about 30L of fuel in the tank. Insert the cleaned plastic pipe from the fuel filler port to the bottom of the fuel tank, and gently blow the gasoline at the bottom of the fuel tank to roll over to achieve the cleaning effect.
The above cleaning method can only be used for diesel tanks, not for gasoline tanks. Because the friction between the compressed air and the tank wall can generate static electricity, and gasoline is flammable and explosive, even in the severe cold conditions of -30 ℃, a tiny spark will ignite the gasoline, causing a safety accident.
