Fuel filler pipe cover

[dida4g]

So I've had 2 R400 with covers and I notice that my ZS doesn't have a cover.
I'm guessing these covers were on the "not needed" pile along with underseal for the fuel tank.
(1st pic had more dirt there, took pics when I was nearly finished.)
Trip to the scrappy, R45 & ?5 later it's sorted.
