Leak Flushing connector 2011 Sea-Doo GTI

[Fischwalla]

Noticed that my 2011 GTI takes on water while sitting in the lake. Brought home and filled hull with water. There is an obvious leak @ the Flushing Connector. I am new to jetski's - but I'm thinking that the connector needs to be tightened. Any advise on the process? Thanks in advance...!
