FUEL SYSTEM 5-5
#
A small amount of fuel may be released when the fuel
feed hose is disconnected.
Place container under the fuel feed hose with a shop cloth
so that released fuel is caught in container or absorbed
in cloth. Place fuel soaked cloth in an approved container.
6. Squeeze the fuel primer bulb until you feel resistance.
Turn the ignition switch “ON” for 3 seconds (to operate the
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 the fuel pressure.
7. Measure the fuel pressure in line at cranking or idle speed
operation.
Fuel pressure: Approx. 255 kPa (2.55 kg/cm
2
, 36.3 psi)
8. Stop the engine and wait 5 minutes.
9. Read residual fuel pressure in line.
Residual fuel pressure:
200 kPa (2.0 kg/cm
2
, 28.4 psi) or higher

As the fuel feed line is still under high fuel pressure,
make sure to release fuel pressure according to the
following procedures.
• Place container under the joint to catch fuel.
• Cover the joint with rag and loosen the joint nut
slowly to gradually release fuel pressure.
10. After measuring the fuel pressure, remove the fuel pressure
gauge.
11. Reconnect the fuel line.
12. With the engine not running and the ignition switch “ON”,
check the fuel system for leaks.
