Been stripping and modifying the fuselage on my project Kitfox 4 and was wondering what the purpose of the 2 tubes circled in the attached picture are for. They are located between the firewall and the instrument panel. I don't think they were used on my airplane and before I cut them out I wanted to know what their original intended purpose was. Can anyone shed light on what they are for?

Thanks.
