Did you see the photo of the underside of wear the thermostat go's that's the only difference, do you know what the purpose of the hole is(weep hole?)

Thank you for the information I like how you do the drawings you should write manuals

I'm not sure what hole you are referring to. If you are talking about this:

That is likely features that were added to the casting so that the part could be held in a fixture for assembly. Weep holes are not external in cooling systems. Sometimes thermostats have a small hole in them that is referred to as a weep hole, but those are to allow air to move past the thermostat when it is closed. If there was any weep hole open to the outside of the engine, then your cooling system would leak coolant constantly.

Do I see the cam driven hi-pres fuel pump in black? And what is the purpose of the ~3/8” hose barb aft of the yellow dip stick?
Again, thanks very much for the image it does tell me much. Do you have more say of the back side?

Is this a test❔

The big red arrow is the high pressure fuel pump.
The open hose barb (green arrow) is one of the two hose couplings for the heater core circuit in the HVAC system. There will be a small diameter hose that goes from there to the heater core that will be on the firewall.

Thanks @JTR19 the fuel pump /cover you have marked is exactly what I was looking at and thinking it might be..
the hose barb is directly below the hp fuel pump. To me it looks threaded into the intake manifold.

hopefully, I’ll get to look at one in detail Tuesday. It’s studying Texan right now on its way S from Detroit.
