fuel tank filler neck vent hose

Does anybody have any suggestions where I can find a new fuel tank filler neck vent hose for a 96 Buick Park avenue or will this be a junk yard used part only? I have already checked ebay,autozone and rockauto to no availability.

In June of 2015 I replaced a tank on a '95 LeSabre (same tank) and had to repair the steel filler neck.

The vent line running alongside the filler was replaced with fuel/evap rated hose attached to the steel neck with straps. You might be able to do the same.

What size of vent hose do I need to purchase?

It would be best to measure. As I recall I used a 5/8" PCV/EVAP hose and stretched it over the steel pipe, then clamped. A '96 could be different.
