That saxo pump actually come with a remote filler in some models. It could sit down on the valence or something and you could extend the tube to suit..The Horizontal layout is a good idea for P6. My Astra unit is vertical and it makes it rather tall if you need to keep the tank on top. Shame there are no Saxos over here in the antipodies...
I'm thinking of including a small pressure tank (probably from a brake system) to ensure there is a bit of steering should the power go off...
