DESCRIPTION

The

transfers
fuel
from

the
tank
to
the
carburetor
in
sufficient

quantity
to
meet
the

engine
require

ments
at

any
speed
or

load

and
held

FUEL

PUMP

TESTING

A
fuel

pump
is

operating

properly

when
its

pressure
is

within

specifica

tions

and
its

capacity
is

equal
to
the

engine
s

requirements
at
all

speeds

Pressure
and

capacity
must
be
deter

mined

by
two
tests
while
the

pump
is

still

mounted
on
the

engine
Be

there
is
fuel
in

is

made

only

when

To

make
this

pro

ceed

as
follows

1

Disconnect

place

install
a

it
is
an

indication

that
