PETROL PUMP
AC DELCO pump reference E/PE 4.777
Auto-regulating diaphragm lift and force pump
operated by eccentric on camshaft.
This pump is fitted with (I device which enables it
to function on re-cycled petrol. This re-cycling is
effected by means of a by-pass .( 1 ) fitted on the
carburettor cover.
Excess petrol supplied by the pump returns to the
tank across an orifice calibrated from 0.8 to 0.9mm
in the by-pass union (1).
PETROL PUMP OUTPUT
(I) Otitput nil, maximum pressure : 325 mbars (4 7 psi).
b) Output through open carburettor float needle
valve.

INSTALLATION OF PETROL PUMP
Fitted on the crankcase with :
one (( Phenoploste P12 )) spacer 5 + 0.1 mm thick.
two (< SOCOID a> paper gaskets fitted dry.
Tightening torque for petrol pump nuts :
21 mN ( 2.1 m.kg ).( 15 l/4 ft.lb )
CHECKING THE STROKE OF THE PUMP PUSH-ROD
a) With the pump removed and using (I depth gouge A,
take the measurement between the upper face of
the spacer ( with paper joints ) and the camshaft
eccentric in its high position and in its low
position.
This measurement should be :
- Upper position of eccentric 27.4 ? 0.35 mm
- Lower position of eccentric 32.4 rk 0.35 mm
b) Measure the length u a a) between the spring stop cup
and the tip of the pump control push-rod.
This length should be :
a = 4.5 mm minimum
