In such a situation, a complete cleaning of the system is required. If cleaning is carried out carefully, the likelihood of re-emergence of microorganisms will be minimized.
1. Completely empty and remove the fuel tank.
Drained fuel must not be reused. Wash it thoroughly and flush the inside of the tank with clean diesel fuel. Highlighting yourself with a flashlight, make sure that the inner walls of the tank are absolutely clean. If it is not possible to completely remove all deposits by flushing, resort to steam cleaning - having achieved a satisfactory result, rinse the tank again with clean diesel fuel.
2. Disconnect the fuel supply and return lines from the injection pump, remove the fuel filter and flush the fuel lines with clean fuel.
3. Replace the fuel filter, reinstall the tank, reconnect the fuel lines to the original, and fill the tank with clean diesel fuel. Remove air from the system (see Removal of air from the fuel path of a diesel engine). At the first stage of vehicle operation, make sure that the power supply system is fully restored.
Corrosion products, as a rule, do not enter the high-pressure fuel pump, lingering inside the fuel filter. If, however, it is suspected that the pump is dirty, it must also be thoroughly cleaned. Do not attempt to independently carry out this procedure - entrust its implementation to car service specialists.
Moisture present in the atmospheric air can condense on the walls of the fuel tank, from where it penetrates into the power system path. Diesel storage tanks (including both large tanks and vehicle fuel tanks) are more susceptible to moisture formation than gasoline storage containers, since the vapor pressure of the latter is noticeably higher. To minimize the ingress of condensation into the fuel, keep the tank full at all times and try to avoid long periods of vehicle downtime.
You can always buy special additives in car accessories stores that serve to prevent the appearance of microorganisms. Manufacturers of high-quality fuels themselves add this kind of additives to diesel fuel.
If signs of microorganism development are found in the fuel, notify the owner of the gas station, of which you are a regular customer, and, at least for some time, use the services of another station.
