Finally check clearance between pipes and/or hoses, as shown above.
If clearance between cruise control pump and power steering hose is less than 10 mm (0.39 in), proceed as follows:
1. Move clamped section (A) (refer to Fig 6 ) down to a point where pipe is close to crossmember.
  Pipe-to-crossmember clearance: 10 mm (0.39 in), min.
2. Check that clearance between cruise control pump and power steering hose is at least 10 mm (0.39 in). If it is not, bend section (B) down until a clearance of at least 10 mm (0.39 in) is obtained.
