1.5L REVOTORQ BS VI ENGINE 94 Fuel System Priming Procedure If the performance of the engine is affected due to the presence of the air in fuel system (commonly known as air lock), then defect can be removed by bleeding the fuel system. This can be done by pumping the priming pump by hand. Start engine and check for fuel leakage. Rectify if necessary. Check for smooth running of engine. Whenever replacing fuel filter, use priming pump to complete the fuel flow circuit. NOTE Do not loosen the HP lines for bleeding the air from fuel system. Bleeding of the fuel system should be done only using priming pump. F. FUEL TANK AND FUEL TANK UNIT The Fuel tank assembly consists of the fuel tank and the fuel level unit. The fuel tank is used to store the fuel. The fuel level unit consists of float and a sensor. Fuel level sensor assembly provides the signal to indicate the fuel level in the tank. As the float arm assembly moves with respect to the fuel level in tank, resistance at sensor varies accordingly.
