To remove the fuel pump, the screw clamps of its inlet and outlet hoses are loosened, the hoses are removed and their ends are jammed with process plugs. Unscrew the fastening nuts and remove the fuel pump from the engine. Remove the gaskets and the heat-insulating spacer with the pusher.
Before installing the pump, check the protrusion of the pusher. For proper installation of the pump, two of the three gaskets below are used: A - 0.27-0.33 mm thick; B - 0.70-0.80 mm thick; B - 1.10-1.30 mm thick. Installation is carried out in the following order. Install the heat-insulating spacer with the pusher, placing gasket A under it (pic. 26), and a gasket B is placed on the plane in contact with the pump. Dimension d is measured (maximum protrusion of the pusher, set when the engine crankshaft is slowly cranked). If the size d is in the range of 0.8-1.3 mm, the pump is fixed. If the size d is less than 0.8 mm, then instead of the gasket B put the second gasket A; if dimension d is greater than 1.3 mm, then gasket B is replaced by gasket C. Dimension d is checked again and the pump is fixed to the engine. Gasket A must always be placed under the heat-insulating spacer. Gaskets A, B and C are interchangeable with the corresponding gaskets of previous car models.
