      *a Arrow Stamp

      Secure the hydrogen tank tube joint in a vise between aluminum plates.

      Note


      • Be careful not to scratch or damage the seal portions or threaded portions.

      • Do not overtighten the vise.

      • If the hydrogen tank tube joint has been dropped or subjected to a strong impact, replace the hydrogen tank tube joint and hydrogen tank pressure sensor with a new one.

    2. Install the hydrogen tank tube joint supply bracket to the hydrogen tank tube joint with the 2 bolts.

      Torque:
      13 N*m  { 133 kgf*cm, 10 ft.*lbf }

      Note

      If the hydrogen tank tube joint has been dropped or subjected to a strong impact, replace the hydrogen tank tube joint and hydrogen tank pressure sensor with a new one.

      Tech Tips

      Install so that the direction of the arrow stamped on the hydrogen tank tube joint inlet bracket is pointing toward the hydrogen tank pressure sensor side.

  3. TEMPORARILY TIGHTEN HYDROGEN TANK TUBE JOINT


    1. Temporarily tighten the hydrogen tank tube joint to the front center hydrogen tank frame with the 2 bolts.

      Note

      If the hydrogen tank tube joint has been dropped or subjected to a strong impact, replace the hydrogen tank tube joint and hydrogen tank pressure sensor with a new one.

  5. INSTALL FUEL TUBE GROMMET


    1. Engage the claw and install a new fuel tube grommet to the front hydrogen tank frame sub-assembly LH.

    2. Engage the clamp and connect the No. 4 hydrogen tank tube to the fuel tube grommet.

      Note


      • Do not damage or deform the No. 4 hydrogen tank tube.

      • If the pipe protector material of the No. 4 hydrogen tank tube is damaged so that the internal pipe itself becomes visible, replace the No. 4 hydrogen tank tube with a new one.
