I would like to edit the previous post to add that I do not like this set up as it is. The second pic on that page you will see a $2 funnel from an autopart store. Plan is to cut the lid, fit the funnel from the inside of the lid, drill the 2.5" hole in the top of the funnel to lift the light off the hood/water line. I will be moving in a couple weeks and will then stop using the gooseneck attached to the rear glass on the tank. I may hang it from the celing or build a small bracket on the wall for the gooseneck to attach to. As it is installed now, the lid is not the easiest to open.
