2006 F200 Water Pressure Fitting

Does anyone know where the water pressure port is on a 2006 F200 4 stroke yammie is? I have the gauge all hooked up and the tubing run to the engine I'm just not sure where to hook it up engine side. Also a part # for the fitting would be great. Thanks in advance!

ttt anyone know

The port is just behind oil dipstick below intake manifold, use a 14mm wrench to remove plug. If you are using Yamaha's water pressure gauge use 688-83667-00-00 Pressure sending unit. If you are using an aftermarket gauge use MAR-WPRES-AD-TR adapter fitting.
