INSTALLATION SERVICE POINTS
"
AA FUEL HIGH-PRESSURE HOSE CONNECTION
1. Apply a drop of new engine oil to the O-ring.
Caution
Be sure not to let engine oil enter the delivery pipe.
2. While turning the injector, high-pressure fuel hose and
fuel pressure regulator to the right and left, install the
delivery pipe, while being careful not to damage the O-ring.
After installing, check that the hose turns smoothly.
3. If it does not turn smoothly, the O-ring may be trapped,
remove the injector, high-pressure fuel hose or fuel
pressure regulator and then re-insert it into the delivery
pipe and check once again.
4. Tighten the high-pressure fuel hose to the specified torque.
Tightening torque: 5.0 ± 1.0 N⋅m
INSPECTION
Check the following points; replace the part if a problem is
found.
INTAKE MANIFOLD CHECK
1. Check for damage or cracking of any part.
2. Check for obstruction of the negative pressure (vacuum)
outlet port, and for obstruction of the water passage or
gas passage.
3. Using a straight edge and thickness gauge, check for
distortion of the cylinder head installation surface.
Standard value: 0.15 mm
Limit: 0.20 mm
