High Pressure Fuel Pipe Removal Note

CAUTION:

• When removing the high pressure fuel pipe, the end of the high pressure fuel pipe may be damaged because the clearance between the high pressure fuel pump and the high pressure fuel pipe is small. Be very careful when handling the end of the high pressure fuel pipe so as not to damage it.

• If the high pressure fuel pump is removed with the high pressure fuel pipe installed, the high pressure fuel pipe and fuel distributor may be damaged because of the excessive force caused by the spring force of the high pressure fuel pump. The high pressure fuel pipe and fuel distributor must be replaced if they are damaged. Always remove the high pressure fuel pipe before removing the high pressure fuel pump.
• I pay attention so that a dent and a vice are not put on the plating in the high pressure fuel pipe surface at the time of SST use.

NOTE:

• Depending on the vehicle's period of manufacture, it is either equipped or not equipped with a high pressure fuel pipe cover. If the cover is removed, it is not necessary to reinstall it because the part has no effect on the vehicle's functions and performance.
