The silver braided flexible hose is the filling loop.

Turn the blur plastic head 90d and hopefully you will hear water filling the system.

You may also find the valve on the other end needs opening if this doesn't work, in this case it would be the plastic head has broken off, so might need a small spanner or grips to turn it.
