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.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I have a 2002 C4S and just recently replaced the fuel pump. Overall relatively easy job, not much to say about it here. However, on the new pump I bought I noticed the manufacture date on the box (September 2020, which is reasonable since I bought the pump in August 2021) but also an expiry date that is 2 years after the manufacture date. See picture below. I used google translate for translation from German to English. Can anyone explain to me what the expiration date means? I have not seen it on any other Porsche part, so this is why I am surprised. I am certainly hoping that the pump will last significantly longer than through September 2022 .

POST 2Original post

It�s probably more of a �best if used by� type of date... Perhaps there are diaphragms or something in it that dry out or tend to malfunction if they�re not in contact with fuel for extended periods of time... I wouldn�t worry about it... Life�s too short

POST 3Original post

Pure speculation, but it's "use by", not "use until", which implies to me that it has limited shelf life rather than useful life. Maybe it has something do with soft parts degrading if they aren't soaked in fuel?
