A. Disconnect the rubber pipes from the vapour
bleed control valve.
- BEFORE DETACHING THE RUBBER PIPES, APPLY A LA-
BEL ON EACH PIPE SO AS TO REFIT THEM IN THEIR
ORIGINAL POSITION.
B. Remove the vapour bleed control valve from the
fuel tank by undoing the relevant fixing bolts.
C. Visually inspect the vapour bleed control valve
for cracks or damage.
If damage of any kind is found, replace the valve
with a new one.

bleed control valve. Make sure that there are no
air leaks by injecting compressed air at 29.4 kPa
(0.3 kgf/cm2) into the pipe on the fuel tank side,
with the pipe on the activated carbon filter side and
pipes on the atmosphere side closed.
In case of air leaks, replace the valve with a new
one.
E. Check the vapour bleed control valve for reduc-
tions.
a) Check that there is no air continuity in the pipe
on the atmosphere side by blowing air inside the

tivated carbon filter side closed.
