I sincerely hope so. To be honest, I would probably have bought the MERLIN hoses for their original appearance and because I still have a small doubt about the fuel-proof qualities of Silicon hoses. However, one should not ignore that a fuel filler hose is not filled with fuel 24/7/365. It only gets touched by fuel during a refill and the fuel quickly evaporates.
Silicone hoses are always unwise for fuel.

petrol tanks should have the mandatory roll over fuel protection rather than remotely at the deck as the filler
hoses seem to often get torn from the deck filler with any impact and a roll-over drenches the occupant(s). Not fun with
sparks flying about. Easy to rectify. Many marques, with the same problem, insert one way valves into the hose, near the
tank entry. Cost negligibly and no expertise required.
There is nothing terribly wrong with the MMC filler hose materiel, except they have limited flexibility and their shape is
unhelpful. They pleat, as can be seen for the images and that makes filling the tank a pain. They also age badly, like all
rubber and few attend to that, a task required every few years. A shapeable flexible forever filler hose made from a wiser
materiel is far more prudent and cheaper, in the long and short run.
