Check Valve Help

Hi guys,
I'm re-doing the trunk area firewall on my 77 308GTB,
and have replaced the fuel tank vapor cannister braided lines
and forget to take a picture of this check valve before I removed it.
Could one of you look at your 308 and tell me the proper mounting position of the check valve bracket.
above, or below the mounting bolt.
Thanks!

Well, I'll just mount it like this till someone can tell me different.

Looks a little better back there.

Sorry Dave!

I was remembering mine mounted in a different location! I'll check both cars, and see where it lies........

Seems like mine was above the right rear wheel liner, on a tube rail there, IIRC.
