I took the tire off, popped out the shroud, disconnected and reconnected things, wiggled things around, and then hoof'ed it to the local gas station to get 5 gallons of gas with the idea of trying to put fuel in while I still had access to the area.
Leading evidence: 'Reconnect things, wiggled things around' (no explicit attributable resolution; this is a reported action or suggestion).

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.

My 2000 996 had that dreaded 'blowing across the top of a bottle' sound coming from the passenger side fender, and the associated mass air check engine code, and in general the engine acted like a motor with a vac leak.. so I bought and installed a new vent value, cleared the code and the car runs friggin awesome.
All was well till I stopped to put gas in it and the car says no way. I stood today for about 10 minutes and managed to dispense about 2.34 cents worth of gas.. how much actually made it into the tank and how much ended up on the ground is a matter of debate.. but what IS clear is something is not right.
I'm going to pull the tire off and have a look after work.. I did a few searches that said something about a valve at the base of the filler neck, and an E6 fuse.. the E6 fuse is good.
Any other suggestions? Is it possible I may have inadvertently reversed the vac lines that attach to the valve? Any other things I should check on a 2000 996?
Any suggestions or tips are greatly appreciated!
Vacuum leaks suck don't they Frank?
And it took 10 minutes to get $2.34 (I presume less than a gallon?) worth of gas. Last time I had that problem the nurse screamed, "catheter time!"
Hope you find a solution. I'm sure other will jump in to help. It's a shame your first post on Rennlist is regarding a problem. We're kind of a social group here in the 996 forum. Welcome!
Thanks for the words of encouragement and suggestions.
I have done some googling and saw the "upside down pump" trick worked for some.. but unfortunately, didn't work for me.
I'm about to head home and pull the tire off.. I'm hoping that it's just something stupid like I connected the vac lines backwards or something.. I should probably go home and get a can of gas to fill up so I can put some in there to test it before I get the car all put back together.
Being unfamiliar with the dreaded sound in question and puzzled by the term "vent value" that appeared a couple of times, I had nothin'.
However, Pelican is smarter than I am, and this paragraph sounded like it might be useful to you:
"There is a one way check valve on the air purge line into the canister to stop the emissions from flowing back out to the environment (see Picture 1). If the vent valve does not open you will have a very difficult time filling the car, and if the valve does not close the car will think there is a vacuum leak in the system and cause all kinds of problems starting with your CEL staring at you."
Sounds like either your installation job wasn't quite right or the replacement valve is not functioning properly.
That is indeed the devil in question. In the Pelican Tech article, they refer to it several times as a "fuel line vent valve", so that's just what I've been calling it.
I took the tire off, popped out the shroud, disconnected and reconnected things, wiggled things around, and then hoof'ed it to the local gas station to get 5 gallons of gas with the idea of trying to put fuel in while I still had access to the area.
Perhaps the Porsche Gods took pity on me after humping a 5 gallon can of gas uphill for a mile and a half, but the car gave me no troubles fueling from the 5 gallon can. So I double checked and quadruple checked that no lines were snarled or pinched as I buttoned things back up, and here's to hoping the issue is resolved.
I have read some threads that suggest a person should hear a "click" when pressing in the little fuel door flap going into the fuel delivery tube thing-a-ma-bob.. but I'm not sure if that pertains to the 2000 model year cars. Seems that when people have this issue, people chime in with solutions for a wide range of 996 vehicles, that may or may not pertain to the 2000 cab.
