gas smell from 1968 911L

Check the gas tank, both for possible pinhole rust areas and where the fuel level gauge is attached. That gasket may need to be replaced.

englishkid,

Are there any leaks on your garage floor?

I had the same thing recently in my '67 and noticed a discoloration on the garage floor that made me investigate further.

My problem turned out to be the rubber fuel line in the middle of the car. From what I have read/seen Porsche put a rubber fuel line in the mid section of the car to join the two metal lines to accommodate for body flex. Of course with age its going to crack and leak.

Get underneath the mid section of the car (unless you are made of paper or have a pit you will need to jack the car up - please make sure you take all the safety precautions required) with a torch and take a look at the line. You should see something like this:


I recommend using a torch because the first time I looked at the line I didnt have the torch and couldnt see how bad it really was.

It is also worth checking all your other lines.

I have also been told that the fuel smell may just occur if the o-ring on the fuel cap has past its use by date. It is worth checking this too (a new o-ring is a few dollars).

Best of luck

BIG CAUTION HERE!!!!!!!! - When he sez use a "TORCH", I think he's referring to what we refer to as a Flashlight. NEVER use a open flame Torch around a fuel leak!

nice one bob! no naked flames i promise, cheers from the other side of the drink, ben

search on vapor + emissions

if the above are not the problem, then your gas vapor lines in the trunk are old & stiff -

I'd replace theALL flexible fuel lines every 20 years or so no matter what.

there are some really ugly pics of engine fires floating around the bbs...

It seems something was lost in translation - a torch or flashlight is the same thing here. Best not to use a blow torch, smoke or work in an area that is not well ventilated (watch out for those gas system pilot lights).

Replace the gas cap - $31 here a year ago.
Cured the fuel stink straight away !

Cheers,
Dennis.
