anti syphon valve

[1993 celebrity 4.3L]

Would someone know where the anti syphon valve would be on a 1993 4.3 merc. The boat is an 18' celebrity. I'm hoping it's not at the tank since it is not easiely accessible. Any help would be appreciated.

That is usually where it is.......
Where the fuel line goes from horizontal to vertical....
