Just rebuilt my L69 and I noticed there is a piece missing from my vacumn system. I believe it is the ported vacumn switch to my EFE on my Y pipe. I looked all over the place and I cant find a place for another switch. There is one on my water neck along with another sensor ( is that the coolant temp sensor?) The diagram shows a switch but I cant find it. Is there a picture or a website that would help me with this?

Any help is appreciated.

There are 3 things that screw into places at the front of the motor.

In the water outlet, there are 2 things: the coolant temp sensor, which screws into the smaller hole in the water outlet; and the EFE Thermal Vacuum Switch, which screws into the larger hole.

In the intake manifold, next to and in front of the water outlet, there is one more. It is called the Canister Purge Thermal Vacuum Switch.

Which one is missing?

 

It's the canister purge TVS. It looks like someone plugged the hole with a pipe plug. Thanks for your help it is appreciated very much:hail: :rockon:
