Preheat oven to 350 degrees F. Line 2 loaf pans (10x5x3-inch) with parchment paper.

In a large bowl, blend together the pumpkin puree and sugar on low speed with an electric mixer. Add eggs and mix well.

Mix in coconut oil, orange juice, and vanilla extract.

Add baking soda, cinnamon, pumpkin pie spice, salt, and half of the flour. Mix until just combined.

Blend in the remaining flour until combined. Stir in walnuts.

Divide the batter between the two lined loaf pans, then bake uncovered for 60-65 minutes, until a toothpick inserted into the center comes out clean with a few moist crumbs.

Cool for 10 minutes on a wire rack before removing from the pan.
