Looking for some assistance or guidelines. Has anyone installed flush fuel caps on a SS-7. There has to be a better way than using what kitfox provides...the wingtanks are showing imho their design age and need some design improvement....for eg RANS, ZENITH, VANS all provide flush fuel caps....any advice would be appreciated to assis me on making my decision aka Rans S-21 vs Kitfox SS-7
