TM 10-4930-250-13&P (2)  Latch  (8)  engine module (9)  to pump-engine frame  (10). (3) Clamp  exhaust pipe  (1) to  exhaust manifold   (2). (4) Connect  pumpage  over  temperature  cable  (3) at  engine module  connection  panel  connector  B   (4).  Couple together   adjacent   dust  caps. (5) Connect   fuel   supply   line   (6)  and  fuel  return   line  (7)  at engine  module. (6) Check  that throttle  control  is  at  maximum  position  (fully   right). 1. Position   liquid   fuel  filter-separator   (figure  2-3,  7) 4-5  feet from  puMp-engine  module  (3)  with  inlet   facing  fuel transfer   pump. m. Position   the  accessory module  (8) between  the pump-engine  module  (3)  and the  liquid   fuel  filter-separator    (7) so that  operator   has  a clear  view   and  easy access to  all  system  components. n. Connect  the  3 "  x  6'  discharge  hose (9)  between fuel  transfer  pump  discharge  (10)  and liquid   fuel  filter-separator (7)  inlet  (lower   port).   Rotate discharge  hose as required  to  remove  any  kink  or  bend.  Open  shutoff   valve  and unisex  coupling   valves  on  discharge  hose. o. Connect  the recirculation   manifold   (11) to  the  liquid   fuel  filter-separator   (7)  outlet  (upper  port)  and open the manifold   unisex  coupling  valve.  Do  not  open  3"  unisex  coupling  of  liquid   fuel  filter-separator.    Rotate  manifold so that  the 2"  unisex  couplings   are  facing  the  fuel  drums  and the  unoccupied  3"  unisex  coupling   is  facing  the area  selected  for   the  fueling   points. AAFARS    fuel  hoses are not  supplied  with   scuff  jackets.   Therefore,   hose handling directly    affects  the useful  life  of  the  hose.  Do  not  drag  hoses over  an improved   or abrasive   surface.   To  the  extent  possible,  hoses should  be  rolled   and  unrolled during   setup or  evacuation   to prevent   abrasion. NOTE The  3"  x  50'   discharge  hose  has a 3"  coupling  on  one end  and  a 2"  coupling   on the other.   This   is  the only  hose in  the system  that  can  only  be laid  out  one way. p. On the  3"  x  50'   discharge  hose (12),  identify   the  3"  unisex  coupling  and connect  the  discharge hose to  the  3" valved   unisex  coupling   of  the recirculation   manifold.    Open  unisex  coupling   valves  on  recirculation   manifold   and discharge   hose. Figure   2-3  indicates  the use of  ten 2'   x  50'  fuel  discharge  hoses to  supply  four   fueling points.   This   is  the maximum   number  available  but  actual  set up may  require   fewer.   One hundred  feet  (100  ft  t30.48  m])  of  separation is  required  between  fueling  points. q.     Using  2"  x  50'  discharge hoses (13),  elbows  (14)  and tees (15)  as required,  lay  out  discharge hoses to the selected  fueling   points.   Open  all  unisex  coupling  valves  as connections   are  made. r. Establish  recirculation   path. (1)   At  the  fuel  drums  (1),  connect two  2"  x 6'  suction  hoses (6)  to non-valved  couplings  (2)  mounted on the 2-12
