(12) Fuel is delivered to the injector through the  inlet  connector.    Fuel  pressure  is  controlled  at  this point by a connecting line and pressure regulator. (13) The  second  connection  with  the  clean plastic line is the injector drain connection which carries drain fuel from the injector back to the tank. (14) Fuel  is  delivered  to  the    vial  during  a measured    number    of    strokes    as    recorded    by    the counter. 13-14.      FUEL   INJECTION   PUMP.      To   test,   adjust, replace,  repair,  overhaul,  and  rebuild  the  fuel  injection pump  for  Code  "A"  or  Code  "B",  refer  to  figure  13-20 through 13-25 and proceed as follows: a. Test   and   Calibration.      The   fuel   pump   should   be tested   using   the   fuel   pump   test   stand;   refer   to paragraph b then proceed as follows: (1)   Remove   the   fuel   pump   and   mainshaft   cover from the assembly as follows: (a)   Remove   the   speed   switch   in   accordance with the Operator/ Crew and Organizational Maintenance manual. (b)   Disconnect   the   fuel   pump   line   from   the pump shut-off valve. (c)   Disconnect   the   throttle   lever   linkage   from the throttle lever. (d)   Disconnect    the    shut-off    valve    electrical connections. (e)   Disconnect   the   pump   cooling   line   to   the check  valve  elbow  (1,  figure  13-24)  on  the gear pump. (f) Remove the capscrews securing the mainshaft cover to the engine assembly. (2)   Install the fuel pump in the fuel pump test stand mounting    bracket    leaving    about    1/16    inch (0.0625  mm)  between  fuel  pump  coupling  and test stand drive coupling. (3)   Squirt  some  clean  test  oil  into  the  gear  pump inlet   hole,   so   pump   will   pick   up   faster,   then connect suction line. (4)   Fill the fuel pump housing with clean test fuel oil through the plug hole on 13-37
