Percy, I can't tell about your hoses from here. Braided-stainless-reinforced plastic lines pretty much all look alike. But inside are the real differences: The original lines had/have translucent whitish poly-tetra-fluoro-ethylene (teflon) hose and use the braid as reinforcement & protectant against weathering and external-object damage. Others use poly-sulfone plastic (not translucent) that are higher temp rated than teflon. The fittings were/are 6061-T-6 aluminum with 410-stainless steel hose attachment parts, as sold under the Aeroquip brand. They are aircraft flight-certified and test loaded to over 3000 psi burst pressure for dash-3 and -4 sizes. They work fine for brakes & clutch hydraulics and are monstrous-overkill for automotive fuel, cooling or vacuum systems. The 37-degree cone fittings do not seal well against AC freons. The slick teflon lines flow 4- 5% more fluids at any given pressure than other plastics.
There are visually identical hoses available in which NONE of the listed plastics or metals are used. On our Sept '72 car, there was a stock braided-metal hose used as part of the fuel or smog system. It was visible from the engine compartment and ran across the rear firewall above the engine screen to- I think- the charcoal canister. Since our canister and the hose have been gone for decades, I can't really remember. Inside the braid was a cheap rubber hose crimp-fastened to fittings and the braid was dull tin-plated mild steel. It leaked. I've found others that use brass inner hose fitting parts. They seem OK but cannot mix-&-match.with stainless Aeroquip stuff. I stay away from those. YMMV-
