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 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. -Jim 40134 In a message dated 6/13/2007 12:53:04 P.M. Eastern Daylight Time, scottmschmidt@yahoo.com writes: That is a very good question.

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?

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!

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.

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.
