Wife called saying the Mythic Dually V10 Church Van smells like gasoline. By the time I got there a half an hour later the smell was pretty much gone. I drove it home, no smell to speak of. What could make the strong odor of gasoline come and go?

The EVAP system can be an issue.

What year is it? Does it say OBD-II or OBD-I under the hood?

 

1999. Should be in my signature, but yesterday I noticed that my signature was not at the bottom of all my posts
