(6) Wrap threads on nipple (18) with antiseize tape.  Install nipple in tee (7). (7) Wrap  male  threads  on  bushing  (20)  with antiseize tape.  Install bushing in tee (7). (8) Install   90   degree   fitting   (12)   in   bushing (20). (9) Install tee (7) on elbow (17). (10) Connect  hose  (10)  to  straight  fitting  (11) and 90 degree fitting (12). NOTE Use  a  thin-walled  wrench  (NSN  5120- 00-288-8714)  to  install  swivels  in  valve manifold. (11) Install   two   swivels   (2   and   6)   in   valve manifold (9). (12) Wrap threads on one end of hose (5) with antiseize tape.  Connect that end to tee (7). (13) Connect  other  end  of  hose  (5)  to  swivel (6). (14) Wrap threads on one end of hose (3) with antiseize  tape.    Connect  that  end  to  pressure  regulator (1). (15) Connect other end of hose (3) to tee (4). (16) Wrap nipple (8) with antiseize tape.  Install nipple in pressure regulator (1). (17) Connect nipple (8) to swivel (2). 5-4. Rotation     and     Blow     Hoses     and     Fittings Replacement a. Removal. (1) Tag  and  disconnect  hose  (1)  from  swivel (2) at valve manifold (3) and elbow (4) at hose bulkhead (5).  Remove hose. NOTE Use  a  thin-walled  wrench  (NSN  5120- 00-288-8714)   to   remove   swivels   from valve manifold. (2) Remove   swivel   (2)   from   valve   manifold (3). NOTE First  and  third  hoses  in  bulkhead  have elbow  and  swivel.    Second  and  fourth hoses only have elbows. (3) Remove   elbow   (4)   and   swivel   (6)   from hose bulkhead (5). NOTE Blow  hose  at  rear  of  drifter  connects  to elbow.        All    other    hoses    connect    to swivels (4) Tag  and  disconnect  hose  (7)  from  swivel (8) in drifter (9) and hose bulkhead (5). (5) Remove swivel (8) from drifter (9). b. Installation. (1) Wrap   male   threads   on   swivel   (8)   with antiseize  tape.    Install  swivel  in  drifter  (9).    If  installing elbow  for  blow  hose,  ensure  that  elbow  points  toward striker bar end of drifter. (2) Connect   hose   (7)   to   hose   bulkhead   (5) and swivel (8) in drifter (9).  Remove tag. (3) Wrap   male   threads   on   swivel   (6)    and elbow (4) with antiseize tape.  Install swivel and elbow in hose bulkhead (5). NOTE Use  a  thin-walled  wrench  (NSN  5120- 00-288-8714)  to  install  swivels  in  valve manifold. (4) Wrap   male   threads   on   swivel   (2)   with antiseize tape.  Install swivel in valve manifold (3). NOTE Route all hoses behind feedshell so that they will not interfere with drifter movement.    Ensure  that  hoses  are  not twisted or kinked after installation. (5) Connect   hose   (1)   to   elbow   (4)   in   hose bulkhead    (5)    and    swivel    (2)    in    valve    manifold    (3). Remove tag. 13
