This is not a probability of success.

No CEL, but while the car is apart for other maintenance I have been checking for problems, especially with the normally hard to access stuff.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I have observed that the diaphragm on the cut off valve is leaking slightly where circled when I apply slight pressure or vacuum. Am I assuming correctly this is not proper operation?

POST 2Original post

It should hold a vacuum. Sounds like it needs to be replaced, did you get a CEL?

POST 3 / ORIGINAL POSTEROriginal post

No CEL, but while the car is apart for other maintenance I have been checking for problems, especially with the normally hard to access stuff.

Good move, I had to replace the valve and even with the alternator removed, there was little working room. Check you vacuum canister, mine was cracked and would not hold a vacuum.
