Help finding O-ring

[LiftedBlackHD]

Inside the engine mounted fuel filter housing is a piece of black plastic with a spring attached to it. On the very top of it there is a small green o-ring. Does anyone have any idea what the part # is for that o-ring?

P.S. It's not in the blue spring kit.

Thank You

Can't find the part number for the o-ring but here is the part number for the whole fuel filter stand pipe/check valve assembly: 3C3Z-9T289-AA

Thank You, that is the part! I wish I could just find that damn o-ring!
