I could not find an older post I saw to update, so I am starting a new post about the quick connect fittings for the engine flush port in the engine well. The company that makes these quick connect fittings is CPC (Colder Products Company) I know the male coupling fitting that screws on to a garden hose is correct. The female panel mount that is mounted to the boat is either a 3/8 barbed fitting or a 1/2 inch barbed fitting. I am pretty sure it is the 3/8 barb, but I am not at my boat right now to verify. I ordered the male quick coupling with female garden hose threads from FreshWaterSystems.com. They arrived in two days.
The fitting part numbers are:
HFCD261257GHT Valved Female Thread Male Coupling Insert 3/4 FGHT (Female Garden Hose Thread)
HFCD16657 3/8 male hose barb valved panel mount female coupling body
HFCD16857 1/2 male hose barb valved panel mount female coupling body
