Nice work, AS. I own a Roto-Flare tool, but don't much care for it because it leaves ridges where the two halves of the dies come together. I only bought it for the selection of tube diameters. I flared almost all of my tubing with the IMPERIAL ROL-AIRģ 37į TUBE FLARING TOOL. In tight spaces, this MINI TUBE CUTTER is a life saver, too.

That is some wild plumbing...

Once complete, you will need to crawl over the fuel tank and into baggage compartment and access various components on the back side of the rear bulkhead via the center panel?

I'll stick with easy access carburetors.

I would crawl across the hot desert sand buck naked for FADEC.

Yes, but the Bing carburator acts as though it is FADEC. Single lever opertion with automatic mixture control and no carb heat to worry about. To the pilot - I think operating either carb or iS version of the 912 will be very similar - just master the throttle control...

Actually it is! It's the main fuel pump, aux fuel pump, etc. Some of the tubing comes already completed, and some is done by the builder.

FADEC is much more than what the eyes see, what the hand does, and how the engine performs with a "single lever".
In art terms the 912ULS could be a "work of art", however the 912is would then be considered a "masterpiece"!

I've been thinking more about this... Anybody got a photo of someone sprawled out in the baggage compartment reaching back behind the bulkhead trying to change filters or high-pressure pump once the airplane is completed?

Not being facetious - just having hard time imagining how contorted it must be. A lot of guys are getting up in age and not quite as spry as we used to be.

Iím still building, but have the plumbing installed and tail cone removed so havenít experienced the Houdini acrobatics that will be involved getting back there yet, but to replace filters etc., the Maintenance Manual indicates removing the entire pump/filter assembly and working on the bench for replacement. Requires disconnecting two of the fuel lines and the six screws, accessible from inside the baggage compartment, to remove the assembly. Itís all on a mounting plate. Still not looking forward to the first time I have to do so.

My flare tool is very similar, though instead of a giant "wingnut" handle it has a sliding T bar (think bench vise). I had to flare several lines in place at my fuel selector, since I'm using a duplex valve in a non-traditional mount--I wanted an installation with no hard 90s on the suction side and to do that I had to bring the valve down and forward. It still fits under the stock cover (at least on the sides).

One trick I found was to get one side flared, then pull the line through the grommet and angle it to where I could access it, then flare the other end.

Of course, on one I forgot to install the ferrule before making the second flare.

And then on the remade line, I put the ferrule on and forgot the B-nut.

Third time's the charm, right?
