Do you smell gas in the garage?

[npvpositive]

Perhaps a dumb question, but does your 911 smell of gas/petrol? Since I got it I have always been able to detect a faint gas/oil smell from my car, I can pick it up as soon as I open the garage door . . . is that normal for an early 911?

Thanks

Had this issue myself

My 2 cents

I think all old cars have a bit of oil/gas odor but you should check your fuel system -
start with the small things like gas cap gasket
follow your fuel system from the front (leaking fuel pump)
and the fuel lines and connections back to the engine
and all your fuel lines/connections/fuel filter in the engine bay
and if MFI your injection connections or carbs for any leaks

do you have your cold start hooked up ? it can leave fuel in bottom of your air cleaner housing so make sure all those connections on the back of the air filter housing are good and no fuel pooling in the bottom

Mine was a leaking fuel pump and once I sourced a new one (getting hard these days I hear) it stopped the leak and the smell

Good luck

With my 911, no. But with the 912 and the Sunbeams, I don't notice it, but my wife does say she smells it.

The day I got the Porsche, Mayo replaced all the fuel lines first.
The first week I got the '71 Suburban, I had the fuel lines replaced.
Although I haven't smelled fuel, I just got the '66 Mercedes fuel lines done.

Get the point?

And yet it always ends up being the dang $18 gas cap!

(note: this is in no way a suggestion that old gas hose should not be replaced. In fact, I had an intermittent stalling that ended up being the hose from the bottom of the tank to the pipe that goes back - it would collapse on itself. And, that was the ONLY hose that I had not replaced).

euro cars without charcoal canister have a tendency to have gas smells. Gled

Thanks guys. I suspect some of the old fuel lines may be perishing so I'll start with them.

Let's see if I remember this right. Several of my cars have had gas smells and the culprit was always a leaky plastic box mounted under the hood on the firewall. They all looked fine, but when I tested them by running fluid through them they all leaked at the seams. I glued them and in each case the smells went away. I'm sure someone else can tell us the name of these boxes.

My '69 911T stinks if gas, the garage skinks of gas and i'm getting a little concerned that this could turn into a dangerous situation. The smell is strongest after I've been driving, if it's been sitting in the garage for a couple of days it's not as noticeable. I have many oil leaks from the engine but I don't see any obvious gas leaks?

One of the first places to check is the small black box under the dash. It's been a while, but as I recall it's on the bulkhead on the left side of the car. Held in with a rubber band, it's easy to remove. Run some water through it to see it leaks. I've had gas smells in two cars and in both cases it was a leaky box. I just dried it thorougly then sealed it with some kind of sealant that gas won't dissolve (don't remember what specifically) and voila! Gas smell gone.
