I just completed installing the larger Canadian Windshield Washer Fluid Tank. I had to plug up a hole about 1" on the bottom and a smaller hole to the side of the tank. Those were there because the Canadians have Headlight Sprayers and who knows what else. In total there are 3 holes where we have only 1.
If you are wondering what the purpose of the larger tank is.... it is for more fluid capacity. I want to be safe and make sure I have enough fluid for the Water Injection kit and for my windshield. I tapped the old tank so both would work and I have done the same with the new one. I used a Tank Tap from Devil's Own this second time around. I believe this new tank can hold at least a gallon of fluid were the old tank would hold a little more than 1/4 gallon.
I used some Fiberglass cloth and JB plastic weld to close up the holes.


Here is a comparison shot of what the tanks look like next to each other. There is a huge difference in capacity.


Here is a shot after I Plasti Dipped the tank and left a strip so I could see the fluid level easily. and also the tank installed. No leaks!
