Read evidence and context

Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Discussions that suspect a cause: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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 1Original post

My PSE button stopped doing anything. Tracking it down, the Change-over valve works fine, and I have located a burn hole/vacuum leak in one of the braided-covered vacuum lines to the exhaust valve. Since I'm repairing figured I may as well replace the vacuum lines from COV down to silencer. But access is very tight. Any suggestions to how to reach these best? And anyone have part numbers for these lines - I can not find them online parts information. thanks bill

POST 2Original post

I subscribe to Mitchel service manuals which while not that simple to use or understand do help figure out solutions.

POST 3Original post

Both of my PSE valves move freely, spring loaded open but only go to halfway closed when vacuum applied. I suspect a leak in a line or one of the valves. Checking the vacuum at the COV (Cross Over Valve) it's only 5 in-hg, is that normal for the vacuum system?

This is a source reference. Confirm exact model applicability in the original material.
