Relieve pressure in the fuel pipe line to prevent fueloutflow.
(Refer to GROUP 14 - Service Adjustment Procedures.)
Caution
Cover fuel pipe line with rag after relieving pressure ascertain pressure may still remain.16.REMOVAL OF DELIVERY PIPE, FUEL INJECTOR AND

regulator.
CautionDo not drop injector when removing delivery pipe.
INSPECTIONNllMCAl
Check the following points; replace the part if a problem isfound.
AIR INTAKE PLENUM
(1) Check air intake plenum for defect or cracks. Replace ifdefective
or cracked.
(2) Check load (negative pressure) of drain port. Check
cooling water and jet air passages for clogging. Clean if
required.
(3) Check deflection of installation surface with straight edge
and feeler gauge.Standard value: 0.15 mm
(.006 in.) or less
Limit:0.3 mm (.012 in.)05AOOB4
