It's connected to a metal vacuum line that runs from the valve up to the top/passenger side of the engine. Between the hose nipple on the EFE valve and the metal line there is a short piece of high temp vacuum line that connects them. Regular rubber vacuum line will degrade quickly that close to the hot exhaust.

I will also point out that if you wish to eliminate the EFE valve you can use the open metal "donut" that is used on later TPI engines (which do not used an EFE valve). It takes up the same space and performs the same function of connecting the pass. exhaust manifold to the y-pipe as your EFE valve does, but it's just an open metal donut. Flat on one side (to exhaust manifold outlet) and flared on the other (to the down-pipe).

 

Looking for a pic of the EFE or a replacement EFE?

 

like what it looks like installed i cant seem to find it

 

Look between the outlet of the passenger side exhaust manifold and the Y pipe.

 

ok i checked there is nothing there its direct im going to the junkyard today
