The fuel tanks on second-generation EMD locomotives are
        
        
          made by welding the end sheet onto the fuel tank from the
        
        
          outside. This means the end pieces are slightly larger than the
        
        
          sides of the tank. To simulate this, cut two pieces of .010” sty-
        
        
          rene sheet that are .500”x1.5”. Glue one piece on each end;
        
        
          once the glue is dry, hold a scrap piece of .010” styrene sheet
        
        
          against the oversize end piece and trim it flush as shown in
        
        
          [46]. Once the rough cutting is done, use the same scrap of
        
        
          .010” styrene and a small file to shape the new end sheets to
        
        
          their final profile as seen in [47]. Sand with fine sandpaper as
        
        
          necessary to remove any marks left by filing. You should now
        
        
          have a .010” lip around each end of the fuel tank.
        
        
          Now build new sides for the frame from pieces of .020”x.080”
        
        
          styrene strip. Add additional layers as necessary to match the
        
        
          rest of the frame. Test-fit the motor to make sure the styrene

          strip does not interfere with it sliding into position. Putty and
        
        
          sand the joints; once everything is dry and smooth, glue a
        
        
          piece of .020”x.020” styrene strip along the bottom of each
        
        
          side of the frame. This simulates the frame being made from
        
        
          two parallel I-beams.
        
        
          Following photos, add the applicable pieces from the Cannon
        
        
          & Company 2156 fuel tank detail set. Drill a #56 hole in each
        
        
          side of the fuel tank .250” from the front for the fuel filler. Drill
        
        
          a #66 hole on each side for the top fuel gauge.
        
        
          I also used the fuel tank brackets from this set rather than the
        
        
          brackets included in the Details West SD45 detail kit. Be aware
        
        
          the fuel tank brackets cover a couple of screw holes in the
        
        
          frame. You may want to modify the brackets so the screw holes
        
        
          are not blocked, or glue them in place after painting and final
        
        
          assembly. I simply did not install one screw and modified the
