DV TW? Emmissions sticker
What does this mean? 1980 f150 l6. The hose comes from the PCV valve hits the circular 3 plug "diverter?' splits off, ones plugged, the other goes to coolant temp vaccuum. it was plugged with a screw? I am trying to figure out where its supposed to go.
I also have an EGR valve coming from the bottom of the carb body. There is no hose attached, where one should be, Any one know where this hose should be coming from?

I hooked the hose to the main vaccum under the carb body. seems to work. There was a hose with a screw in it as well.
Still have no hose for EGR valve Anyone know where this hose should be coming from?

turn, be connected to another VCV but which ultimately gets ported vacuum from the
carb (meaning no vacuum is supplied at idle). There may also be various other vacuum-
operated devices inline, I forget what they're called and what they do.
I think DV-TW is some sort of relay & delay valve.
There should be a sticker on your radiator support under the hood showing the vacuum
hose routing.
