Fuel fill cap for my 2016 Forester 2401W MBS

[tomrlansing]

I lost my fuel cap and clearly the filler neck is NOT sprinter. So after three round trips to Amazon thought I would ask if anyone has purchased a cap and what/where/part number.
Thanks

We just twisted up an old red shop rag and stuffed it in the filler to keep fuel from splashing out and rain from getting in the fuel. Of course, with today's modern vehicles which have a closed fuel system to prevent evaporation from causing pollution, I suppose that's not a good idea.

I am using the wad rag trick and wonders, no Ck engine lights! Still like a cap though
