Fuel pump
The fuel pump is attached with two nuts through a heat-insulating spacer and an O-ring. Pump body and cover are one-piece, i.e. The design of the fuel pump is non-separable and cannot be repaired.
Checking the discharge pressure of the fuel pump
Connect the control pressure gauge hoses to the fuel pump and to the carburetor.
Start the engine and measure the discharge pressure on the pressure gauge, it should be within 0.20-0.25 kg / cm2
The pressure at the outlet of the fuel pump is not adjustable. If the pressure drops below the acceptable level, replace the fuel pump.
