2002 Mercury Sable Hose ?

[spk2000]

My daughters car had a slight misfire and I thought I could hear a vacuum leak. Here are 2 pictures showing the location of this hose. I am calling it a hose but it does not look like a hose more of an electrical socket on the end. Does anyone know what this part is called?
I plugged it over a post sticking out with a hole and the rough idle/ misfire went away.

Thats the source vacuum connection. Those smaller tubes go to things like the fuel pressure regulator, EGR solenoid and other things. Should fit tightly on a large port on the upper intake manifold.

Ok thanks. It is very loose fitting so I plan to replace it. Never had one go bad before

I'm cheap, hose clamp would be my first fix attempt. It might be a NLA part.

Ditto, hose clap or if too wide, and if that "post" has a flared end on it, a piece of solid core electrical wire tightened below the flare should work.

I also agree with repairman54 that it is unlikely that Motorcraft still stocks that, if they ever did. You could probably DIY cobble something together by getting same size boot, then make new holes for the two vac lines or put them in with a plug of RTV sealant holding it together.
