The subject of the invention is a system of supplying combustion engines with fuel, alternately with petrol / diesel oil or LPG, especially engines with multi-point or direct injection.According to the invention, in the supply system there is a petrol / diesel oil tank 1 and a LPG tank 2. A sealed glass 3 is placed in the LPG tank 2, which by its upper plate 4 is fixed in the upper plate 5 of the cup 6, placed in the LPG tank 2, At the inlet to the sealed glass 3 there is a solenoid valve 7, which controls the switching of fuel from petrol/diesel oil to LPG. To one input of the solenoid valve 7 there is supplied petrol / diesel oil through solenoid valve 13, and to the second input LPG is supplied - the electrovalve 7 opens the LPG flow instead of gasoline / diesel oil and vice versa. From the sealed glass 3 fuel: petrol / diesel or LPG is fed to the high pressure pump 8 and then to the engine 9. The low pressure branch at the outlet of the high pressure pump 8 is connected to the manifold 10 of the small and big fuel circuit. The small circuit valve 11 is connected to the sealed glass 3, whereas the large circuit valve 12 is connected to the LPG tank 2.
