What Motorhome Water Filler Cap with Hose Connector for hymer

[fat haggis]

Hi I have just taken ownership of a lovely Hymer 655 Starline. And it’s my first hymer. Had a rimor before. What a lovely Mach it is wife loves it so win win. The hose water connector I tried the one I had for the rimor but no fit. Can somebody please point me in the right direction to one that fits the 655 Starline. Thanks

Have you tried this one ? It's meant to be universal now.
