Fuel Filter

So, on the past long weekend my driver and me have bought and changed the fuel filter. It was spoilt because of the bad quality diesel sold on Russian petrol pumps. Last week the temperature fell below zero and this resulted in a condensate forming in the fuel tank. Water reached the fuel filter and the car was displaying an error continuously on the computer screen. The challenge was to locate and understand which one of the two filters was affected. It could have been the one under the hood or the one which is situated at the exit of the fuel tank. Obviously, as the fuel tank was under the car it would be quite difficult to change the fuel filter there, as we have not got such equpment, which could lift a 2.7 tonne car to a height of 2 metres. So we knew that the system was interconnected but the fuel filter at the exit of the tank is much stronger and  universal and rarely needs replacing and therefore we hoped that be replacing the one under the hood the error on the screen would disappear. Under the hood it was situated under the second fuel pump, which extremely difficult to unscre. We had to borrow an electric scew driver from the electricians to do it, as by ordinary human hands and a spanner it was impossible to do. We changed the filter, which is quite small in size( I expected it to be bigger) and th error disappeared. Again, I have enriched my knowledge of automobile mechanics. Our future plan is to monitor the condition of the car and if something breaks try to fix it without the help of official Toyota workshops, which by the way do not always do the job and just leave the old filter but reset the computer with a special program. The old fuel filter is displayed above. ( a clean one for a landcruiser is supposed to be grey)
