According to the parts listing (attached pic) the same fuel pump with angled outlet was used from 1937-1954, although that may be a replacement unit, not necessarily original equipment. The repair kits, have a break between 51 and 52 (second pic) however, indicating that original equipment pumps were different. I know that the fuel pump on my '51 has straight through inlet and outlet with glass bowl. I have no idea whether it's original or not, but I believe the originals had glass bowls. I used the number stamped on it (1523089) to get a repair kit from Then and Now Automotive.
