Hi Jeff,

Wondering if you were able to locate/test/replace ORVR valve. I have 2003-S with fuel refill problem. No issue starting and no coke bottle noise. I think it’s ORVar valve but can’t seems to find it on sending unit. I do have option code M664 (which means I have ORVR system and this bugger is hiding somewhere.)
