Preheat oven to 350°F (175°C).

Grease and flour two 9x5x3 inch loaf pans.

In a large mixing bowl, sift together flour, baking soda, ginger, cinnamon, nutmeg, and salt.

Create a well in the center of the dry ingredients.

Add oil, eggs, water, vanilla, and pumpkin to the well.

Beat all ingredients together until well combined.

Pour batter evenly into the prepared loaf pans.

Bake for 60 minutes, or until a wooden skewer inserted into the center comes out clean.

Let cool in pans for 10 minutes before transferring to a wire rack to cool completely.
