CHECKING &EL SUPPLY
PRESSlJliE AND’CIRCUIT
TIGHTNEh
As for [-33) except for 1.7
electronïc ~ injection engines which
require the following procedure
May 1988
E,ffect checking as follows:
1. Circuit pressure checking
a. Disconnect fuel delivery tube @
downstream from the damper @
b. Connect a gauge by means of a
T adaptor between damper @ and
tube @ previously disconnected.
c. Detach tube @ from pressure
gauge 0.
This is in order to avoid that any pos-
sible anomalies on idle rotation speed
could cause unusual readings.
d.‘ Start the engine; at idle speed check
that fuel pressure value is:
280 i 320 KPa
(2.8 c 3.2 bars; 2.9 + 3.3 Kg/cm’)
e. Reconnect tube @ to pressure
gauge; at idle, fuel pressure should
drop of 0.5 bars approximatively and
then rise again when throttle valve Will
open. Should thisoccur, please check
any possible tube @ depression
leaks.

3 Throb damper
4 Tube delivery to fuel distribution manifold
00-14
2. Checking on circuit tightness
a. With pressure gauge plugged, and
with engine on idle,throttlethedelivery
tube immediately downstream from
pressure gauge, de?ecting a pressure
increase up to
400 KPa
(4 bar’s; 4.1 Kg/cm*)
(do not let the pressure exceed this
value)
b. With pressure on 2.5 bars check
that fuel delivery tubes and fittings do
not show leaks.
c. If fuel pressure does not reach
this value and if no leaks are detected
check the filter and/or the pump
ooeration.
CHECKING AND POSSIBLE

ADJUSTMENT
As for (Alfa]
except for 1.7 ele-
ctronic injection engines which require
the following procedure
1. Check table sliding
Checkthattheacceleratorcontrolcable
slides freelv in its sheath
2. Check table clearance
a. With the accelerator pedal re-
leased, check that the accelerator
pedal on control lever has an axial
clearance of GI = 1 f 2 mm.
b If necessary, proceed to adjust the
table clearance extracting the
adjustement clip 0 in order to give
tbe prescribed clearance to the table,
