Attention. Observe fire safety regulations.
When the fuel pressure is not correct, check the fuel pump and then check the pressure regulator.
1. Check the vacuum tube for cracks, cuts and disconnection.
2. At the speed of x.x. disconnect the vacuum tube and install the clamp on it. Make sure the fuel pressure has increased.
- Standard pressure: 320-370 kPa (3.3-3.8 kg/cm2)
If the pressure does not increase, restore the vacuum tube, lightly squeeze the fuel return hose from the pressure regulator to the fuel tank 2-3 times, and measure the fuel pressure again. If the pressure does not return to normal, replace the pressure regulator.
Do not damage the fuel return hose while squeezing it. If the hose is cracked, replace it with a new one.
