once in a while i get a really strong wiff of gas inside the cabin of my 82. I noticed there is a vent tube coming from the filler neck...I'm not sure if this is where the smell is coming from or not.
is this comon?

I have similar experiences, but only when the car has been sitting for over a day and never when driving. When I get in, there's a fairly strong smell of fuel which dissipates quickly. My cousin's '76 Carrera 3.0 had the same smell so I figured it just something that comes with old Porsche ownership

Is there some sort of fuel vapour release system that might be leaking into the cabin? I'm still learning about my car, so I'm not sure...

This may sound crazy, but on '80's cars, try a new gas cap. Guys on another board have written that this has solved the problem.

Funny story about that...
The first DAY I had my car, I was getting gas and i set the cap on top of the pump. I had my back to it while I filled the tank. Some ******* guys behind me [pumping gas on the other side of the pump] reached over the top and stole the cap.
I was 10 hours away from home [I bought the car in North Carolina] so I stopped by a pep boys and got a 6 dollar "Fits GM, FORD, YUGO, PORSCHE" plastic cap. The original was metal.

Could this cheap gas cap be the culprit?

Could be. On the other board, the cause was explained as a poor sealing gas cap gasket. Going to an original cap may solve your problem.

I'm still fighting a similar problem in my '88 930. The gas smell was STRONG. Got a new gas cap last weekend, and the smell has almost gone away now. I'd start with an OEM cap and see if that solves your problem. They're only about $20. Good luck!

I had to replace my gas cap two times, due to gas fumes. The second time was better. They are both German, from the same manufacturer, as far as I can tell. The first one was defective as the "grooves" do not go all the way to the plastic part, so the plastic seal was not compressed enough to make a tight fit. Hope this helps.

Since you have a 3.2L swapped into the '82 let me tell you a good place to check as mine started with the occasional smell and developed into a constant strong smell before I found it. On the back side (towards the front of the car) of the engine from the end of one fuel rail to the end of the other is a rubber hose. That hose gets old and cracks and leaks, eventually it leaks a lot. A new one is, I believe about $50, or you can just replace the rubber with fuel injection hose and some clamps. Its a simple job once you remove the airbox and the heater fan. Maybe not as likely as something near the gas tank, but you should check it just in case.

I had the same problem, and it was worse when the tank was full. The overflow /vent goes to a platic vapor tank in front of the drivers side front wheel. The rubber hose had cracked and would become wet when the tank was full and the gas expanded. easy fix.

So Paul...did you ever find a fix?

Fahrvergnuugen

no, its really erratic. i can't figure out what the problem is. i checked the line that was mentioned and i ordered a new metal gas cap, but it hasn't arrived yet.

i tried sniffing around to see if it smelled stronger under the dash, near the floor, in the trunk, etc, but it doesn't at all. very strange....

keep us posted, okay? And good luck. Must be annoying as all get-out.

I had the same problem. Went to the gas station to fill up. Opened the hood and removed the carpet and began to fill up. Inspected main fill into the tank and saw a very small drip coming from the small vent hose that goes underneath the main filler. Squeezed the hose and found the problem. It had deteriorated just enough to cause the problem. Replaced and cabin is a "Gas free zone"!
