Did you check if the valve gets correct vacuum-signal?

I do not have a vacuum reader but what I did check was if the valve would close w/o any vacuum. So I removed the vacuum line and shut off both ends and drove with hot feet... If anything, the valve is the wrong one (open at zero) or it's definitely broken. I'd go with the last one.

Come to think of it, I may need a valve myself for the Fury... let's see if anyone knows the answer to your question.

The 68 Valve is for Non A/C  You need the vacuum valve.  Even that one doesn't look correct for your car.  But I'm no B Bod expert

Yours is fender mounted and also vacuum.  4 Seasons makes a replacement for your car too.
 
By the way, I have a set of NOS tail light lenses that fits your fury

The non A/C cars don't use a valve in the heater lines B or C at least thru 69.   The cables control the door in the heater box only.

The 68 or 69 valve would replace what you've got just fine.    It might not be factory but it would work.  All you're doing is shutting off the water from the vacuum switch on the dash.

The ones at the top of the page are what Classic Auto Air uses too for their conversions on an A-body since their controlled by a cable still,  We just did one.

So the Bouchillon one is good for my application, is it better than the rockauto one? I ask this because Rockauto is easier to order from here overseas.
I have the chassis repair manual of 1971 and a Haynes for 1971 and both say that Satellites from 1971 with AC are vacuum operated and non AC cars are cable operated. That's why I need the vac operated one :)

I didn't even look at the Rock Auto one before....too lazy!

Yeah it would work too,  same principal.    If it's easier to get then use that one,  just a bit more in price is all.   There's a lot of different valves out there for the different years.   That one is a replacement type & may not look factory but will work fine.
