HiCustomer welcome to Just Answer!.

If you haven't seen this hose already, remove the air cleaner body to check a short section of rubber hose that connects the nylon purge line and the steel body line coming up from below. This hose is pretty well hidden and often evades detection.

It's serviced only with an entire hose harness package (complete with purge solenoid) and runs about $40. Since the hose changes sizes from 5/16" to 3/8" in a span of only three inches, it's kinda special but you can manufacture your own size-changing hose by using an adapter available from most auto parts stores. Look for a 5/16" to 3/8 connector and put short pieces of fuel line on each end. The fuel line will outlast the original type hose by a wide margin.
