I used the overflow as a template for the holes I needed to drill in the tank. This was very nerve racking for me.
I needed to verify the nuts from the bulkhead wouldnt interfere with the rim of the tank. All said and done, I wish I could have drilled the holes close to the rim, however there was interference.
With the overflow finished and the holes drilled I started pluming the supply and return lines.
