Where can I find a detailed vacuum hose diagram for my '90 Taurus GL 3.8L?

My co-worker says I should have a sticker under the hood somewhere with a diagram, but I can't find it (VECI sticker was gone also when I got the car).

I searched my Haynes repair manual with no luck either.

The hose that is severed is coming through the upper center of the firewall between the two heater hoses (I think that's what they are, sorry, I'm a beginner to DIY auto repair).

Like I posted before, I'm asking this because my air only comes through the defroster vents, even if I select floor/vents/etc. Could this be caused only by a severed line, or could it also be caused by general low pressure in the vacuum system?

Thanks,
BMagnusen

The Vaccum hose diagram should actually be on the underside of the hood itself. Usually right in the front center. It should be there, because there is no way anyone could/would want to remove it. Hope that helps.

I looked and there is no diagram on the underside of the hood nor anywhere in the engine compartment at all.

Is there somewhere on the internet that has close-up photos of various engine compartments so I can just visually see the routings of the hoses? Or could someone photograph their '90 Taurus 3.8L engine compartment close-up for me?
