to

the

and

place
a

container
under

Note
that
the
inner

diameter
of
the

pipe
must
not
be

too

small
or

the
pipe
will
be

incapable
of

delivering
the
correct

quantity
of

when

Hold
the
end

the
hose
above
the

level
of
the

pump
and

operate
the

pump
for
more

The

if

or
if
a

reduced

quantity
of
fuel
flows
from
the
end
of

hose
Remove

the
pump
from
the
vehicle
and
test
as
follows

Connect
the

pump
to
a

fully
charged
battery
If
the

pump

now

operates
and

discharges
fuel

correctly
the
fault
does
not

lie
in
the

pump
but

may
be
attributed
to

any
of
the

following

causes

Battery
voltage
drop

poor
battery
earth
loose

wiring

loose
connections
blocked
hoses
or
a

faulty
carburettor

If
the

pump
does
not

operate
and

discharge
fuel
when

connected
to
the

battery
then
the

pump
itself
is

faulty
and

must
be
checked
as
follows

First
make
sure
that
current
is

flowing
This
will
be
indica

ted

by
sparking
at

the
tenninals
If
current
flows
the
trouble
is

caused

by
a

sticking

pump
plunger
or

piston
The

pump
must

be
dismantled
in

this
case
and
the

parts
thoroughly
cleaned
in

petrol

If

the
current
does
not
flow
a
coil
or
lead
wire
is
broken

and
the

pump
must

be
renewed
A

reduced
fuel
flow
is
caused

by
a

faulty

or

The
