Drinking water system hose and connectors

[Udi]

Recently I replaced the drinking water pump in my Hunter 45.
I have to connect an accumulator to the system.
Problem is that there is no room to install them near each other.
For installation (in a bit remote area )I need the original hose and connector.
It looks like the hose is a standard on those boats (2010) and so are the connectors. (enclosed pics)
Any idea where can I get hose (details can be seen in the pic) and various kinds ( E.G: T shape / straight connect / L shape and so) connectors.
Thanks.

it is metric pex. Most marine supply shops have them. I needed to replace on on my water heater several years ago.
