4-5 Inspecting and replacing tank vent
NOTE:
Tank vent prevents a vacuum from forming
in fuel tank when fuel in fuel tank is being con-
sumed. When pressure in fuel tank becomes too
high, tank vent releases the pressure.
1. Remove dust cover (Refer to “4-4 Inspecting
fuel tank and line”).
2. Remove tank vent (A) from grommet (B).
3. Connect tank vent (A) to pressure tester 91139
(C).
4. Apply pressure approx. 50 kPa (0.5 kgf/cm
2
) (7
psi). Make sure pressure is stable in range of 10 -
40 kPa (0.1 - 0.4 kgf/cm
2
) (1.4 - 5.7 psi).
5. If it is not in the range, gently clean tank vent
with compressed air or replace with new one.
NOTE:
Do not disassemble valves in tank vent as-
sembly. Damage to valves will occur.
6. Apply negative pressure 20 kPa (0.2 kgf/cm
2
) (3
psi).
7. Tank vent should pass air freely without holding
any pressure. If it does not, replace tank vent with
new one.
