I don't remember if anyone contacted Van's with the oil sender location as a problem. Since it is a Rotax part, installed by Rotax, I doubt Van's would have assumed a responsibility or provided a recommendation.

I am aware of the perceived issue... I say perceived because I have never seen any level of evidence that shows that the sensor mounted on the engine has any effect on longevity.
I am aware of a few sensor failures, but there has never been any evidence to suggest that remote mounting would have prevented those failures. It seems that most of the frenzy to change the mounting location resulted from the recommendation of Lockwood. Is this because they have data they haven't shared (I have an open line of communication with a couple of the key tech. people there), or because they were searching for a solution to sensor failures and thought that sounded like a good idea?
My original question was based on a bit of surprise that the install kit uses hose barbs and clamps for a rather critical hose installation. That in it self is not bad but it does imply what type of hose is probably being used.
Personally I see this mod as attempting to cure a possible, but uncertain disease, with a potentially fatal one.
All of the critical hoses (oil and fuel) on the RV-12 FWF are fire sleeve protected, which gives them a high level of protection against abrasion/wear through, etc. If this particular hose is not well protected (I don't know whether it is or not) it induces a critical (and maybe un-necessary) hose that is highly dependent on being properly routed, restrained and protect, to prevent the hose from being compromised over time. If it ever is compromised, it will be a serious event.
