1.  Reliability (no reflection on the reliability of Richard's pump - but
the plastic  oil lines can become brittle and leak)
2.  Little room for any sizable oil container on my firewall
3.  Probably having to remove cowl to fill/service oil tank (although I am
certain I could figure a way around this)
4.  More weight and complexity (not much true, but a bit)
5.  Forgetting to fill the oil tank (yes, could forget to mix oil, but
haven't yet)

6.  Not certain of effects (if any) of the "Plugs Up" orientation

Hi Ed;
        As I pointed out in the previous post, your concerns regarding #1 is valid.
For #2 & #5, I planned to use an oil reservoir from a snowmobile as they are approx. 4litres and have a low level sensor built in to illuminate a light on the panel when approx. 1litre remains. Unfortunately I have no room on the left side of the engine due to the turbo and intercooler, but have plenty on the right side, however this will require a longer feed line with less positive gravity feed.

        Right now I always remove top of cowl for pre-flight, so level check and fill is not an issue, however when I have enough flight hours, I can imagine that I will be less eager to do this, so #3 certainly might become an issue.

        Of course #4 always is an issue, but I'm more concerned about it being too far forward, moving my CG up a little.
