5-5 FUEL SYSTEM
B
A small amount of fuel may be released when the fuel
feed hose is disconnected.
Place container under the fuel feed hose or 3-way pipe
with a shop cloth so that released fuel is caught in con-
tainer or absorbed in cloth. Place fuel soaked cloth in
an approved container.
3. Squeeze fuel primer bulb until you feel resistance.
Turn ignition switch “ON” for 3 seconds (to operate fuel
pump), then turn it “OFF”.
Repeat this (“ON” and “OFF”) procedure 3 or 4 times to pres-
surize the fuel system and then check fuel pressure.
4. Measure fuel pressure in line at cranking or idle speed op-
eration.
Fuel pressure : Approx. 235 kPa
(2.4 kg/cm
2
, 34.1 psi.)
5. Stop engine and wait 5 minutes.

FUEL PRESSURE INSPECTION
1. Relieve fuel pressure in fuel feed line. (See page 5-2)
2. Connect special tools (pressure gauge, pressure hose &
pressure joint) between fuel feed hose and 3-way joint pipe
as shown in figure.
Clamp hose securely to ensure no leaks occur during check-
ing.
