When winterizing my 2007 Volvo Penta GXI-G with DPS-A 1.95 this weekend, I noticed that a high pressure hose that comes through the transom and connects to a white round plastic fitting in the back of the stern drive had broken off. Pictures attached. I have tried to search for this part on parts diagrams online without any luck. Does anyone know what this part is or what this line does? Any thoughts are much appreciated!
