Jared----we've plumb the FT60's in just about every imaginable location, and then some. Firewalls, engines, tunnels, near the flow divider, wires out the side. I cant remember anyone having any issues. Some of the guys at Team AeroDynamix have theirs mounted very near the flow divider, in a vertical position, with the wires coming out the side, pointing aft. Even with all the aerobatics they do, I havent heard of any issues.
I would make a bracket for mounting though. Just my .01 cent worth.

It just doesn't maintain a steady reading.

No issues so far with my install. I am within 0.3 gallons reliably. The fuel line from the Red Cube to the carb is tie wrapped to the engine mount with a standoff about 2-3" long to dampen vibrations.Here is a picture of how mine is plumbed:

I think the manufacture has you install so it so that fuel will tend to puddle in the Red Cube versus drain out, i.e., lowest location: "the fuel line on the outlet port should not drop down after exiting the transducer...can trap bubbles in the transducer causing jumpy readings."

Then what are the two 1/4" machined holes for? The company needs to make up its mind. Its either for hard mounting or its not and that FACT (if it is) need to be blatantly spelled out in the accompanying paperwork. I find the presence of those two holes completely misleading especially if you have to call the factory to get the secret handshake.

what's the justification of not mounting it to a hard surface?

When did they tell you this? I talked with them in 2011 when we were finishing up the RV-3, and was told that while they at one time had problems with vibration getting the bearings, they had changed the design and were fine with mounting it to the engine, to something solid, floating - wherever - vibration was no longer a consideration. We mounted ours toa bracket in front of the sump, and it has been absolutely perfect for over 400 hours now.
To the OP's question - one reason to make a bracket is to allow clearance to make connections. Think in terms of removal and replacement and initial installation of all your equipment - make it easy to work on!

Last Spring. I am struggling to recall the rationale provided, but it wasn't bearings. They made it clear that they wanted it to float and not be rigidly attached. They may have different techs providing different guidance or some are more strongly clinging to issues had in the past. They made it very clear that no harm would come to unit by hanging from the hoses. It made logical sense to me and I decided to mount that way. Seems that the general experience is that the units are robust enough to handle a hard mount.

Wow, we've come full circle then. I can recall when I was looking to install mine that the manufacturer wasn't recommending that it be mounted in-line, and many people here on VAF were uncomfortable about having that weight hang off the aeroquip fittings.
Mine is mounted to an angle bracket that is Adel-clamped to the crossbar between the two gearleg mounts (tailwheel RV-6).

Even if it *does* need to be rigidly mounted, what are the 1/4" holes for? You could probably pick up the entire engine on two 1/4" bolts. Overkill, perhaps? Maybe it's just easier to find a 1/4" x 2" long bolt than it is a 1/8" x 2" long bolt?
