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