I've used gates efi hose for years on a bunch of cars without any issues? The hose was used with 6an push lock fittings all the time but I always used efi hose clamps in conjunction. I never had an issue. Link below to hose I've used. Gates 3/8 efi hose with 6an push lock fittings.
In the first few lines of the first link below it states it won't deteriorate with modern fuels.
