2012 E350 - Fuel filler door won't lock shut
Wife refilled the gas in her E350, then when she went to close the fuel filler door, it wouldn't lock shut. Some further investigation seems to indicate that the switch that activates the lock solenoid has failed. Did some searching but can't find the part number or any directions on how to replace it.
Can anyone point me in the right direction?

The problem isn't that it won't close. The problem is it won't stay closed.
Normal operation is this:
EDIT: I'm a dolt. I looked at it again. Apparently while there is only a little nubbin on the gas cap, there remained about 2" of tether on the filler door. And that 2" wound up on the gas cap rest on the filler door, thus popping it open. Apparently the plunger isn't a switch after all. I stand corrected and eat my slice of humble pie.

QUICK RELEASE PULL:
You can access a Red plastic emergency release handle behind the trunk carpeting.
It's useful when the latch is inoperable.
