Replacement Air pump hoses?

[T-5 Killer]

Does anyone know where to get replacement air pump hoses. I am reisntalling the air pump system on my Cobra and some of the hoses have holes in them. I figure I might have to make replacements out of heater hose or is it to high temp?

heater hose will be fine. Even down at the cats.
