Inline tube

Question, has anyone else had trouble with Inline tube? They do not put part numbers on their tubing, I have a fuel vapor line that is wrong, two piece item, one piece has the correct bends, the 2nd is all wrong, plus it should be 5/16", not 1/4". Their customer service sucks, can't talk to anyone, they encourage email, crickets for the last 3 days.
Had a wrong fuel line 1 year ago, never really got that settled either.
Does someone else do this?
