Lynn,
I don't know if it's a technical or cultural description - but I don't know what a stink wheel is. Can I assume it's a thin metal cutting disk that's needed to cut through the SS braid?
Good ideas coming out of this, which leads to thinking further on the subject.

Just an AN rated stainless braid in a cloth cover. Probably Nitral lined. Silicone lined might work as well. Very tough stuff. Cut with a stink wheel. Shoved onto a smooth tube with a single hose clamp. You can park a truck on it and it won't collapse. In light suction it is 100 times the hose needed to do the job. You could also use many others to the same end. If it will perform in hot oil, it will work. There is no mechanical stress as in a pressure situation. We used the same piece of surplus hose in the Lotus for 4 years. No noticeable degradation. We were constantly letting in fresh air to mix with the oil, and keep the track lubricated.
 
Those tubing bender kits provide many sizes of hose reinforcement for using thin walled hose like bus heater hose for cooling and breathers. It keeps the tight bends from kinking. Used it many times with different hoses.

In "A "are you saying a silicone hose with s spring insert or is it just a hose piece joining two metal tubes together. What I'm concerned about is degradation from heat and oil as well as hose collapse.
