I swapped mine this evening. It is a 5/16" hose and I needed 2 1/2 feet. Cost $6 from autozone.
Here is a photo of how it routes pretty cleanly from the charcoal canister to the TB despite not being molded:
Also, for future reference, here are some of the markings on two different fuel lines. They are both SAE 30R7 (or J30R7, same thing), but one mentions PCV/EEC while the other just says fuel line:
And finally, I cut open the vacuum hose I was using to see if there was deterioration...looked pretty clean.
Was I ok to keep using? probably. Will I worry less knowing it is the right hose? absolutely.
