Then I assembled the pump assembly and using the backer plate drilled all the bolting holes. I used WD soaked paper towels laying in the bottom to catch the shavings.
Using body tools I flattened out the 3 ridges. Pain in the butt as you can imagine, by flattening out the ridges the top of the opening wants to bow up or bow down because there is no where for the extra metal to go.
And as you can see, the "butter dish" has a hole drilled in it close to the bottom to help hold fuel to the suction side of the pump but still be able to keep full if the fuel level is low.
