See the attach picture of the water pump I purchase and pay close attention to the black plastic inlet and outlet fittings. Do I need to install pipe to hose fittings or can I use the vendor supplied plastic fittings? The reason I ask is the pump came with red FME caps and the black plastic threaded fittings that are flat on (2) two sides. It looks like it could function as a barbed fitting but would be a leak path.
