Regular thinwalled nonarmored rubber hose is usually quite soft and in condition of higher then regulary temperatures it's getting more "liquid". In this situation vacuum together with hose bending are causing situation, where inner diameter is more thinner then necessary for normal flow of gasoline.
To avoid such kind of deformations in hose they are armored between two (inner/outer) layers of rubber hose with nylon or steel based nets. Some type of hoses are armored only from outside.
So armored hoses are keeping their diameters much more better under control.
I hope I have understood correctly this thread before my post.
