Preheat oven to 350.
In large bowl, beat together the sugar, oil, pumpkin, and eggs.
In a medium bowl, stir together the dry ingredients.
Fold dry ingredients into the wet ingredients. Stir just to moisten.
Gently stir in the raisins and nuts.
Pour into a greased loaf pan.
Bake for 35 minutes to an hour (if using convection oven it takes less time). Done when a toothpick comes out clean.
Set pan on a rack for 10 minutes and then turn out the loaf to cool completely.
