Keith -

SAE 30R9 is the stuff that's used with modern fuel injection systems. I've been using it for several years on all of my cars, to replace the old stuff, with no problem.

Although I've seen heater hose used for fuel vapor applications in a pinch (even in late model cars), I prefer to use a hose that's properly rated for that purpose. I'd rather not make a mistake that will be revisited upon any subsequent owner.

Not to digress, but there's even hose rate specifically for use with ATF applications - where other rubber hoses won't last for long.
