Check the Fuel Leakage of the Overflow Pipe
1. Connect the fuel pipe joint (7) of air pressure adjustment
equipment to the eye joint bolt (3).
2. Tighten the valves (4).
3. Connect the air hose to the air pressure adjustment equipment.
4. Adjust air pressure of the regulator (1) between 0.03 and
0.05 MPa (0.3 and 0.5 kgf/cm
5. Open the valve (4) gradually, then add 0.03 MPa (0.3 kgf/cm
4 psi) pressure.
6. Tighten the valves (4).
7. Check the decreased pressure after 4 seconds.
NOTE

• If the decreased pressure is higher than 0.001 MPa (0.01 kgf/
2
cm , 0.1 psi), it means that there is fuel leakage. Replace the
gasket (5), then check the fuel leakage again.
