HIGH-PRESSURE FUEL HOSE INSTALLATION
1. Apply a small amount of fresh engine oil to the O-ring.
Caution
Take care not to let any of the engine oil get inside
the fuel pump (high pressure).
2. While being careful not to damage the O-ring, turn the
high-pressure fuel hose to the left and right and connect
it to the fuel pump (high pressure). After connecting, check
that the hose turns smoothly.
3. If the hose does not turn smoothly, the cause may be
that the O-ring is getting caught. Disconnect the hose,
check the O-ring for damage and re-connect the hose
to the fuel pump (high pressure) and then re-check.
