I´ve tried SKU 4380503 now, but 1,5mm don´t fit - can´t close the tank completely.
I also ordered SKU 2066601 and that one fits well (like the original).
BUT SKU SKU 2066601 seams to be made of a bit harder material and looks like it makes tank disassembly for rewick easier.
Need to try it out a bit.

Trying Kendoo at the moment....
