Horizontal res

[timesavage]

I have been seeing some pretty incredible builds with horizontal reservoirs, and I am on a mission to build an in desk computer. I want to do horizontal, but how do you keep the res's full with no air bubbles? Elevated fill valve? Any help is appreciated.

In mine, it is just fill and bleed, followed by more filling and bleeding until it is full. I just use a barb with a piece of tubing and a funnel to fill mine. You have to have the top of the res pointing up to fill and cap it, or you will lose water. So if you do it in a desk, you will want a mount that is easy to undo to do the final fill (unless you like to turn it on its side)
