I believe that I have broken :mad what is to the best of my knowledge the EFE TVS switch. This part is located on the top left intake manifold and screws into a slot that has radiator fluid in it. The part has two vacuum hoses going to it, now that I broke it, not sure which hose goes on top or bottom. One hose goes to the carburetor and the other to the left wheel area. I can not locate this in my assembly manual or Service manual. If it is pictured/located in the assembly or Service, please let me know where. Any help would be appreciated and where to get one. Thanks in advance!
 
Bear with me..I'm a little confused as to which left side you're talking about. The EFE is on the right or passenger side. The canister purge is on the left or driver's side.
Putting that aside, the part is called a ported vacuum switch. I believe the vacuum source or carb side goes on top. There should be a molded plug to prevent improper hook up.
If it's the canister purge, then the vacuun source goes on the bottom.
I know Standard Motor products sells both: PVS27 is the # for the purple color one, and PVS16 for the blue one.
 
That's OK. I guess you mean the cannister purge vacuum switch then. If that's the case, then the carb side goes to the bottom.
Hope that helps.

Good luck!
