Preheat oven to 350℉. Grease two 9x5-inch loaf pans.
Sift flour, pumpkin pie spice, baking powder, baking soda and salt into a medium bowl.
Combine pumpkin, sugar, apple juice, eggs, oil and vanilla extract in a large bowl; stir well. Stir in flour mixture and ¾ cup nuts.
Spoon into prepared loaf pans. Sprinkle remaining ¼ cup of nuts over top of loaves.
Bake for 60-70 minutes or until wooden toothpick inserted in the center comes out clean. Cool in pans for 10 minutes; remove to wire racks to cool completely. Cut each loaf into 9 slices, then each slice in half.
