High Pressure Fuel Pipe Installation Note
CAUTION:
- Damage or deformation to the end of the high pressure fuel pipe may cause fuel leakage. When installing the high pressure fuel pipe to the high pressure fuel pump, be very careful while handling the end of the high pressure fuel pipe.
- If parts are exposed to fuel, their function may be decreased or a fire may occur. Always wipe off any leaked fuel using a clean rag.
- Do not let foreign materials enter into the high pressure fuel pipe.
- Install a new high pressure fuel pipe because it cannot be reused.
- Temporarily tighten the nuts on both ends until they are seated to the nipple of the high pressure fuel pipe.
- Temporarily tighten the high pressure fuel pipe bracket installation bolt.CAUTION:
- Performing the procedure with the tightening nut angled at or away from the SST shaft could cause fuel leakage because the tightening nut cannot be tightened to the specified torque. Perform the procedure with the tightening nut and the SST shaft parallel to each other.

- 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.
- Tighten the nuts on both ends using the SST.
High pressure fuel pipe tightening torque
17-23 N.m {1.8-2.3 kgf.m, 13-16 ft.lbf}
- Tighten the high pressure fuel pipe bracket installation bolt.
High pressure fuel pipe bracket installation bolt tightening torque
8-11 N.m {82-112 kgf.cm, 71-97 in.lbf}
