Preheat the oven to 325°F. Line two 7x3 inch loaf pans with parchment paper or foil, or grease your baking pans.
In a medium bowl, whisk together the flour, baking powder, baking soda, cinnamon, nutmeg, and cloves. Set aside.
In a large bowl, add the oil, cup of sugar, pumpkin puree, and salt. Whisk vigorously until combined. Add the eggs one at a time, mixing well after each so it is completely incorporated. Scrape down the sides of the bowl with a rubber spatula. Sift the flour-spice mixture over this and stir with the spatula or a wooden spoon until just combined.
Divide the mixture evenly between the pans and smooth the surface. Sprinkle each evenly with 1 tablespoon sugar. Bake approximately 45 minutes. Remove from the oven and let cool.
