I finished a two day Rotax 912 Series service seminar (Leading Edge Airfoils in Lyons, WI) where it was pointed out that a auxiliary fuel pump is recommended in any installation using the 912 however my impression is that most Kitfoxes with the 912 do not use an aux pump (in addition to the engine driven one).

In my Model 5 Tri Gear, I do not believe I have a pump on board other than the mechanical engine driven one. It works fine, but now I'm wondering if I should put one in? Should I be doing fuel flow testing or just keep flying what I have? (It does have a lot of time on it with no known incidents of any kind.)

Another point, is: Should I have a metal header tank instead of the plastic one ? My plastic one works however is a little "weepy" around the pipe joints.
