water filler cap - replacement

[blue-max]

The deck water filler cap - blue plastic has broken. It has the brand name Len  but I am unable to find a new one having this brand. I did buy a replacement cap which  looked the same but did not screw down. Any suggestions  - I don't want to  change the filler assembly  - its too awkward to  get  to  the plastic pipe under the deck

You didn't mention year and model of your boat. This one fit our 2000/2001 boat: https://www.asap-supplies.com/eu/water-deck-filler-cap-305510

Here the original Bavaria spare.
As expected the price is pretty high
