5-6 FUEL SYSTEM
8. After measureing fuel pressure, remove fuel pressure gauge.
9. Reconnect fuel line.
10. With engine not running and ignition switch “ON”, check
fuel system for leaks.
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 ap-
proved container.
4. 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
pressurize fuel system and then check fuel pressure.
5. Measure fuel pressure in line at cranking or idle speed op-
eration.
Fuel pressure : Approx. 255 kPa
(2.55 kg/cm
2
, 36.3 psi)
6. Stop engine and wait 5 minutes.
7. Read residual fuel pressure in line.
Residual fuel pressure : 200 kPa (2.0 kg/cm
2
, 28.4 psi)
or higher

As fuel feed line is still under high fuel pressure, make
sure to release fuel pressure according to following
procedures.
• Place container under joint to catch fuel.
• Cover joint with rag and loosen joint nut slowly to
gradually release fuel pressure.
