While some evap hoses may have been printed with "gas gas gas", all the ones I currently have or have had say "evap" followed by the size. I.E. evap 1/4 or evap 5/16 or "evap 3/8, in a blueish-green paint (ink?) with all being in caps.
Same deal with the PCV hose. Venders sell gas gas gas as correct for that app too, but originals I've seen were either plain black or evap 3/8.
