Take care not to let any of the engine oil get inside the fuel pump
(high pressure) or the delivery pipe assembly .
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

HIGH-PRESSURE FUEL PUMP AIR BLEEDING
1. Run the engine at 2,000 r/min for more than 15 seconds to remove
air from inside the pump.
NOTE
When the high pressure fuel pump is removed, air may enter the
pump. At this time, abnormal fuel pressure causes the diagnosis code
No.56 to be output.
2. After that, check the diagnosis code using MUT-II. If the code No.56
is output for the fuel pressure sensor system, erase it.
