6) Inspection of Fuel Regulator
1. Remove cap 1.
2. Connect pressure gauge 2 as shown.
3. Disconnect thin vent hose from fuel regulator, and connect
vacuum/pressure gauge 4 to fuel regulator 5.
4. Start engine and keep running at idle revolution speed.
WARNING
Before connecting pressure gauge, cover
connection between pressure gauge and
valve with clean and dry cloth to prevent
fuel from releasing.
• Connect pressure gauge ass'y securely.

WARNING
Before measurement, be sure to check
that pressure relief valve is fully closed.
Do not open pressure relief valve during
measurement. Opening the valve allows
fuel to spew out, possibly causing fire.
After measurement, cover hose tip with
rag, and open pressure relief valve to
drain fuel from discharge hose and the
instrument.
Before storing pressure gage, fully close
pressure relief valve.
Fuel Pressure (Reference) :
0.29 MPa ( 43 psi ) [ 3.0 kgf/cm

] ±10%
5. Apply vacuum pressure to fuel regulator 4 to check if fuel
pressure is reduced. If fuel pressure is not reduced, replace
fuel regulator 5.
