Remove the high pressure fuel pipe.

(1)

Remove the high pressure fuel pipe mounting bolt (A).

High pressure fuel pipe function block mounting bolt:

7.8 - 11.8 N·m (0.8 - 1.2 kgf·m, 5.8 - 8.7 lb·ft)

(2)

Remove the high pressure fuel pipe flange nut (A).

High pressure fuel pipe flange nut:

26.5 - 32.4 N·m (2.7 - 3.3 kgf·m, 19.5 - 23.9 lb·ft)

Installation

1.	Install the fuel line in the reverse order of removal.

Install the high-pressure fuel pipe as follows.

(1)	Completely pre-tighten the both side nuts (A) on high pressure tightening area of high pressure fuel pipe while keeping them vertically.

(2)

Tighten the high pressure fuel pipe function block mounting bolt (B).

Tightening torque :

7.8 - 11.8 N·m (0.8 - 1.2 kgf·m, 5.8 - 8.7 lb·ft)

(3)

Completely tighten the both side nuts (A) on high pressure tightening area of high pressure fuel pipe.

Tightening torque :

26.5 - 32.4 N·m (2.7 - 3.3 kgf·m, 19.5 - 23.9 lb·ft)

•	Do not reuse the high pressure fuel pipe.

•	Be careful not to transform the shape of the high pressure fuel pipe.

•	Torque wrench should not be tilt when you tighten the nut.
