 (c)
 Move the valves (30) and/or (50) until the tube assembly (25) is correctly aligned with the valves.

 (10)
 TORQUE the coupling nuts at the two ends of the tube assembly (25) to between 135 and 150 lbf.in (1.52 and 1.69 m.daN).

 (11)
 TORQUE the nuts (45) to between 20 and 25 lbf.in (0.22 and 0.28 m.daN).

 (12)
 TORQUE the nuts on the valve couplings as follows:

 (a)
 TORQUE the coupling nut to the value shown on the coupling.

 (b)
 Lightly hit the perimeter of the coupling with a fiber hammer, then torque the coupling nut again.

 (c)
 Do the torque procedure two times, then torque the coupling nut

 again. R

 D. Installation of the PRV to HPV Tube Assembly
 (1) Remove the protective covers from the hose tube assembly (40) and the fittings on the valves (30) and (50).
 CAUTION : APPLY ONLY A THIN LAYER OF (CP5063) SILICON LUBRICANT TO
_______ THE THREADS OF THE HOSE TUBE ASSEMBLY COUPLING NUTS AND FITTING ON THE VALVES, AND REMOVE UNWANTED LUBRICANT. KEEP LUBRICANT FROM GOING INTO THE HOSE TUBE ASSEMBLY AND VALVES. IF TOO MUCH LUBRICANT IS USED, THEN LUBRICANT MAY CLOG THE HOSE TUBE ASSEMBLY AND ENTER THE VALVES AND DAMAGE THOSE COMPONENTS.
 (2)
 Lubricate the threads of the coupling nuts and the fittings with silicon lubricant (Material No. CP5063).

 (3)
 Loosely connect the hose tube assembly (40) to the bleed pressure regulator valve (50).

 (4)
 Loosely connect the hose tube assembly (40) to the HP regulator valve (30).
