Drilling three holes doesn't seem like it would take over an hour. Well, drilling the holes took about 5 minutes, figuring out exactly where they would go took the rest of the time. I started by drilling the top two 3/16 holes. Measuring over and lining them up evenly with the angle iron. Getting the firewall penetration hole for the filling took a bit. I used two bolts to hole the reservoir in place and marked the hole. Then, I drilled a pilot hole and used a step bit to take it up bit by bit. When it was close, I used a wedge shaped grinding wheel in the drill to take it the rest of the way. I installed and removed the reservoir at least 25 times. I wanted the hole to be JUST big enough.
