Lockable Gas Cap; Ford E-450

[Swimmer]

A web search for a lockable gas cap gave me a couple options on Amazon, but they did not list the E-450. I also saw some reviews noting the vehicles system was giving an alarm code "Fill cap not on" when they switched their stock cap to a locking type.

-->Has anyone found a locking cap that will work on a newer vintage E-450, and did you have any alarm code issues?

-->Also, I found this cover plate and wondering if anyone has used them?

I have used this one and it functions as expected. No error codes.
