Heat oven to 325 degrees.
In a medium bowl, whisk together the oil, sugar and eggs until smooth. Add the banana, pineapple and coconut and whisk well.
Add the dry ingredients and using a rubber spatula, gently fold together the flour into the batter. You want to leave a few streaks of flour and be sure you do not over mix!
Grease an 8x4" bread pan and pour the batter into it.
Bake for 65-70 minutes until he top springs back when touched.
Remove from the pan and allow to cool completely. Bread is best if it has the chance to sit overnight wrapped in plastic wrap.
