If you haven't bought the part yet I have a brand new one I never used that I bought when I was chasing down a fuel leak. It turned out to be the o-ring so the valve has sat in my parts box, in the bag it came in along with a new o-ring since I bought it last year. I paid over $100 plus shipping for it...if you want it for $80 shipped you can have it.

I can double check on my EPC that the same part is used in yours as was in my '98 but am almost positive it is...just let me know if you need it or anyone else wants it PM me.
