Preheat oven to 350 ℉. Prepare a loaf pan by spraying with oil or lining with parchment paper.
In a small bowl, combine the flour, salt, baking soda, and pumpkin pie spice. Set aside.
In a large mixing bowl, combine the pumpkin puree, eggs, vanilla, oil, and sugar. Mix well.
Place one cup of the chocolate chips in a separate bowl and toss with 2 tablespoons of flour. Shake off any excess flour. Fold the chocolate chips into the batter.
Pour the batter into the greased pan and smooth the top with a spatula. Sprinkle the remaining 1/2 cup of chocolate chips onto the top of the loaf.
Bake for 55-60 minutes. Make sure that a toothpick inserted in the middle of the loaf comes out clean before removing the loaf from the oven.
Let the bread cool in the pan. Transfer the cooled bread to a cutting board, slice, then serve.
