Bob---generally speaking, a rubber lined hose from Vans would be Aeroquip 701, identified by a blue anodized fitting and a red collar. Stainless braid over a synthetic rubber liner. Some early hoses were Aeroquip 303, again a rubber lined hose but with a gold collar. Distinctive black cotton cover, with a steel reinforcement braid, a cotton braid under that, then a synthetic rubber liner. Very common in general aviation.
Most teflon hoses use a crimped fitting, generally steel or more appropriate, stainless steel. Vans supplied oil and fuel pressure hoses had steel nuts and generally plated brass collars, as seen from this damaged hose that rubbed on some structure. Their oil and fuel hoses were generally from Stratoflex, and had stainless hose ends. Ours, from -2 through -8 are all stainless hose ends meeting Mil Spec. -10 through -16 uses aluminum made from 2024T3. (Next production run will upgrade to 7075T73).
Since some of you did not build your planes, there may be questions about what type of hoses you actually have. Pics are great for identification. We'll be glad to identify them for you.
