Can you supply me with a Filler Cap for a Steam Wallpaper stripper?

I require a Filler Cap for a B&Q Performance 1800 Wallpaper Stripper & Steam Cleaning Kit. The cap is quite basic i.e. not a safety cap and is approx 30 mm diameter.
B&Q supplied a help no. but this proved to be useless. Can anyone help?
