<p>Just revisiting this issue as it really bothers me. Risk is based on probability and consequence of a failure. As an example, "engine explosion" would have very high consequences, but the probability is low enough that we still fly single engine planes.</p>

<p></p>
<p>In another forum, I asked an acquaintance, who's VERY knowledgeable about NTSB reports and investigations, if I could search for a given component manufacturer by name to see occurrences of FACET pump failures, in this specific case.</p>
<p></p>
<p>The report which resulted had only one Facet fuel pump related failure, in 2005 on an RV-6A. Other incidents that were thought to be fuel related, with Facet pumps, resulted in the pumps working normally on post-crash examination.</p>
<p></p>
<p>For the case in which you were assisting in the investigation, perhaps it was recent-enough that the report hadn't been finalized? Or, if the word "facet" was not used, that would have resulted in a false report as well.</p>
<p></p>
<p>Not doubting your work; I'm just trying to gain as much insight as possible. I don't want to slough it off, but don't want to over-design just the same. Thank You for any additional information you might be able to share....</p> It is a 40105 n pump ..BOBtag:zenith.aero,2018-12-17:2606393:Comment:6577892018-12-17T23:07:50.896ZBob Joneshttps://zenith.aero/profile/BobJones

<p>As I pause and ponder if I will continue at all with my original plan to install the $42 facet pump I bought for my Rotax 912 equipped 701 I’m building, I’m contemplating installing it in a bypass loop, using it only to start the engine, switching it off for flight operations, and replacing it at each annual. </p>

I don't like the stuff but after many years of use I haven't had any problems other than it goes bad pretty soon. I've always been skeptical of the stated problem of attracting moisture. That can be an advantage...the E absorbs the water in solution with the gas/E and it passes harmlessly thru the motor. When we get water in our car tank we pour in a bottle of heat right? Alcohol if I'm not mistaken. I understand if there's too much water the E can separate out with the water and now we got straight gas with unknown AKI. I've never heard of that actually happening; I suppose that scientifically maybe so but in my experience a non factor.The hoses and stuff we got nowadays are usually OK with E so with reasonable care that shouldn't be much of a problem. I did careful takeoff distance on my 701 with avgas and 93 E cargas and there was no measurable difference. I just run the stuff, like it or not.<br/><p></p>
