Are you tired of no being able to see through the side of your coolant reservoir?
Here is mine being held aloft with the New Mexico sun behind it. I don't know how anyone is supposed to see through this thing in dark merry olde England.
One hole drilled in the bottom.
Plumbing supply 1/4 inch connector with high heat silicone.
Brass fitting on the high side.
Painted flat black now that I don't even have to pretend to see through it.
More pictures to follow after mounting.
