I finally had time to put the pieces together last weekend. I wasnt sure how to mount the motor and pump so the shafts would line up for the couplers. The only thing I could think of was to attach pieces of wood together with a thickness of the distance required between the pump and the motor. 3 pieces of plastic decking I had laying around plus a piece of 1/4" plywood did the job. I used a drill press to get a perfect aligned hole all the way through the block. Then I used a hole saw to make a perfect size hole for the pump. I didnt have a size that matched the motor, so I had to go a little bigger on that side. I fastened the pump first, then aligned the motor and fastened it. In the end, it actually worked out pretty well. I am testing right now, but will hopefully attach it to the burner soon.
