<VV> Double Flair SS Fuel Lines- Cunifer tubing?

[Carlton Smith]

Has anyone considered the Cunifer type of tubing used for brake lines. It is
an amazing material that is rigid yet bends easily. I have used in for the
oil feed line on my 65 Corsa Turbo with great success. It also polishes and
plates really well if you want to go that route. Fedhill sells it and is the
best place to buy it in the USA.

Stainless tubing is not a good candidate for single or double flaring -- 
it is too "brittle" and tends to split, although I have managed to do a 
few over the years that held together at least for a while, most went 
into the scrap pile.  That's why most shiny fuel lines are chromed, 
after forming and fitting -- check with your plater before pursuing this 
route, or perhaps check with a local tubing supply and fabrication shop.

I have a preference for the Rigid brand flaring sets, or other name 
brand sets in that identical style.

Although 'Swagelok' has a fine line of fittings, the ones probably most 
commonly available in Corvair fuel line sizes are a compression style 
fitting -- compression fittings are not recommended for fuel lines on 
engines due to vibration loosening and the resulting potential fire hazard.
