Fuel pump
The fuel pump is secured with two nuts through a heat-insulating spacer and an annular gasket. The pump body and cover are non-separable, i.e. the fuel pump design is non-disassemblable and cannot be repaired.
Checking the fuel pump discharge pressure
Connect the test pressure gauge hoses to the fuel pump and to the carburetor.
Start the engine and measure the boost pressure on the pressure gauge; it should be within 0.20-0.25 kg/cm²
The pressure at the fuel pump outlet is not regulated. If the pressure drops below the permissible value, replace the fuel pump.
