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.

I would interpret that to mean that you don't need to swap the fuel rail (return/returnless), but I will check the book when I get home in a while to see if it provided more info that I have since forgotten.

Suggestion
It helps lower the incoming charge's temperature which helps more completely fill the chamber with air and fuel and also lowers the chance for detonation.

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.

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

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

So I picked up a used 3.4l e-gas engine for my 3.4l non e-gas pcar. As I'm tearing it down I noticed that porsche ran the gas through a freon chamber. My question is can I swap the fuel rail, a/c compressor, and chamber over to my non e-gas and keep the box happy? BTW I am running a GIAC file on my box.

The early 996's were AFAIK all non e-Gas so I'm a bit puzzled to read of one with e-Gas. Regardless, if the engine came equipped with what I believe is a fuel cooler (my Turbo has one) I'd try to use that. Cool fuel is important. It helps lower the incoming charge's temperature which helps more completely fill the chamber with air and fuel and also lowers the chance for detonation. The DME will protect the engine by dialing back timing but there's a downside or two to this Best if the DME doesn't have to dial back timing.

POST 3Original post

As I recall from reading the ultimate companion, in cars with return fuel line cars the fuel cooler ensures the fuel returning to the tank isn't overheated. In returnless systems, it's supposed to prevent vaporlock. I would interpret that to mean that you don't need to swap the fuel rail (return/returnless), but I will check the book when I get home in a while to see if it provided more info that I have since forgotten.

There are those benefits as well and they are not insignificant. The point is if the engine is equipped with a fuel cooler ideally it should remain so equipped and the cooler hooked up correctly and working properly. This might require a change to the DME or the A/C controller. A non-fuel cooler equipped car may not be set up to engage the A/C compressor and set it to get the desired degree of fuel cooling.
