Preheat the oven to 350°F and grease and flour the loaf pans.
In a large bowl, combine the pumpkin puree, vegetable oil, water, eggs, and sugar until well blended.
In a separate bowl, whisk together the flour, salt, baking soda, cinnamon, ginger, and allspice to distribute the dry ingredients evenly.
Add the dry ingredients to the wet mixture and mix until combined, checking that no pockets of flour or baking soda remain.
Divide the batter among the prepared pans, using the same pan size and fill level for each loaf.
Bake for approximately 45–50 minutes, checking the center for doneness. Adjust the time as needed based on the loaf size and your oven.
Allow the bread to cool before removing it from the pans and slicing.
