Hangar Flying

I'm just getting started on the restoration of my "new" Varieze and have a question regarding its header tank. I don't see the tank called out in the plans and was wondering if this is an option the original builder put in or, was there a supplement to the plans available for the tank. I really don't see a need for it, except mabey as a little extra gravity feed pressure for takeoff? Anyhow, does anyone else run with one? I'd like to eliminate it but I'm not sure if I should. It's got a C-75 on it so fuel capacity isn't an issue. There's no fuel pump so do the strake tanks provide adequate flow? I'm joining CSA so I can get as much help as possible but any info on this will be appreciated.

Thanks
