lnstall a fuel pressure gauge on the adapter hose that was
set up in step
(4).
Use a suitable
O-ring or
gasket between
the fuel pressure
gauge and the special tool so
as
to seal in order to prevent
fuel
leakage at
this
time.
(6)
Install the special tool, which was set in place in steps
(41
and (5) between the delivery pipe and the high
pressure
hose.
(7)
Connect the
(-)
battery terminal.
{8) Connect the fuel pump drive terminal with the banery
(+}
terminal using a jumper wire and drive the fuel
pump.
Under
fuel pressure, check the
fuel pressure gauge and
special
tool
connections
for
leaks.
(9) Disconnect the jumper wire from the fuel pump
check
terminal
to stop the fuel
pump.
(10)Start
the engine and run at
idle.
('11)
Measure fuel pressure while the engine is running
,at idle.
Standard value: Approx. 27O kPa
12.7
kg/crf,
38 pdl
(?)Disconnect
the
vacuum hose from the fuel
pressur;rc-
regulator and measure fuel pressure
with the
hose
end
closed by a
finger.
Sbndard

33O-350
kPa
(3.3-3.5 kg.zcmr,47-50 pdl
(13)Check
to
see that
fuel pressure at idle does not drop
wen
after the engine has been raced several times.
(14)Racing
the
engine repeatedly, hold the fuel
return
hose
lightly with fingers to
feel that fuel pressure is present
in
the return
hose.
NOTE
lf the fuel flowrate is low, there
will be no fuel pressure
in
the return
hose.
