How tight should the nuts be on the brake / fuel line fitting nuts?
Thanks in advance for replies...

That is a very good question. I have asked this quite a few times and I get a different
answer every time.
>From what I have researched there is no specific torque values. When I toured
Lancair, the engine builder there told me to tighten it until it was snug (you
can feel with when the flared fitting is touching both sides of the fitting
and nut) then go an additional 1/4 to 1/2 turn.
Other comments I have received are:
"Just tight enough that it won't leak"
"Just snug it up and check for leaks"
I actually made some fittings on the bench, tightened them up then took them apart
to check for any tearing or excessive deformation and sort of calibrated myself.
I know that it is more important to have a top of the line flaring tool
and to also not over or under flare the tubing.
You may want to call Bart at Aerosport and ask him.
Good Luck.

I think the torque values are listed in my copy of Standard Aircraft
Handbook for Mechanics and Technicians. I don't have access to it right now so
I
can't tell you what it says.
I used those values and ended up with some leaks so I tightened them "Just
tight enough that it won't leak" and then started the practice of "Just snug
it up and check for leaks". With further experience with a particularly
annoying brake line leak, I found "tightening and loosening the nut several times
before torquing it helped to achieve a tight seal". So there is one more
comment to add to the list.

While building my slow build RV-10 I've also been working on my IFR

Well it came together today. ASEL-IR test passed!, now back to

Is there a way to test the systems prior to completion? I have most of
the break lines in, but since the plane is not on its gear yet it is not
complete, How do I test it.
Same with the fuel system. How do I test it with out the fuel tanks?

A huge congrats to you. Now that you're done, I'm sure you've
gathered a huge appreciation for that type of flying and
navigation. It amazes me how well designed every piece of the
system is, down to the flow and layout of chart info (esp. Jepp).
Everything has it's place, and when you put it all together
correctly, it almost seems like a flawless thing...until
you throw in real weather issues and ice. ;)
Glad you took the time to do it!

It is amazing how the whole system works. Plus I had the pleasure of
learning from the beginning with a GNS 530, which is a huge advantage
in knowing were you are and what's next. Also, Since our panel's
main PFD is a Dynon D-100 I had the pleasure of Turning it OFF for the
partial panel approach portion of my ride. All good stuff,+ I'm glad
to have that experience before laying out my panel in the -10.

I recently bought a torque wrench for sockets. I don't see how it would
work on a line fitting. Does this require a different type of torque
wrench?

Check out 'crows foot/feet' at you favorite tool supplier. They're open
end wrench extensions designed to be used on a socket wrench.
WRT to torque, depending on how you use them, their use requires some
arithmetic conversion, as they can extend the 'arm' that is applying the
torque.

I've been testing my brake lines, as I build them, with a handheld vacuum p
ump. Just plug one end of a line and pull a vacuum at the other with a hand
operated Mitivac. I figure if they will hold a vacuum they should hold bra
ke fluid.
If you go this route, I think Mitivacs are available through a number of so
urces (Aircraft Tool Supply and automotive outlets as well.) I've as heard
the aluminum ones hold up better than the plastic bodies.

Congratulation! And please do share with the group your panel plans as you
