[968 Cab]

Filled up the tank at Chevron the other day – but the pump island sloped a little with the car nose down. Topped up the tank as usual.



As I was driving away, I noticed a strong smell of raw fuel. When I parked the car I immediately noticed a pool of raw fuel forming right below the fuel filler neck – it appeared to be coming out close to the fuel pump area. I did not have time to put the car up to check the pump.



A few days later, I went to start the car – back to normal except for the smell of raw fuel. No more leaking, no raw fuel drips etc. I just crawled under the car and it is now bone dry. Inspected the fuel lines in the engine area and they are all OK. It is obviously around the fuel tank / filler area / fuel pump / fuel filter area.



Any ideas before I start taking things apart? Did I end up with fuel in the carbon canister during the fill up?

I will be following this thread with great interest, as this happens every time I fill up my tank. You are not alone. <img src="/forum/images/smilies/968/wink.gif" class="smilie" alt="" />

968.net had a thread on this - you might try to do a "search". As I recall, several people experienced the same thing and the culprit was a plug of sorts that's part of the undercarriage and one can get to it from the trunk ( found under the carpet / matting ? ) that has some connection to the gas tank or lines.. blah, blah.. Sorry to be so vague, but I know there is specific reference to that problem and a relatively simple solution ( ha, new plug or gaskets ) posted.

Thanks! Forgot about good 'ol 968.net! Sure enough, did the "search" and found this is VERY COMMON with our cars - usually starts from "overfilling" but can be due to:



- cracked fuel lines between the filler and "reservoir" tank hidden behind the carpet above the PS cubby in the Cab trunk

- rotten gasket on the fuel tank sender - pull up the fiberglass matt in front of the spare wheel well in the trunk / under the carpet and the 5" round plastic cap

- loose / weeping hoses around the fuel tank sender - see previous for access

- cracked fuel tank (I hope not!)

- loose gas cap / improperly tightened



But it appears that overfilling the tank can lead to the most common source of raw gas smell. The thing that threw me off was the fuel leaking out from above the fuel pump area. Now that the tank is a little lower, there is no leak, and maybe the raw gas smell is the residual soaking into various nooks and crannies. Hopefully it clears up in a day or 2. At least it was not a leaking fuel line in the engine compartment!



Thanks for all the help!

My neighbor has a 968 with the same problem, he took his into a local Porsche repair shop and they found a cracked breather hose at the gas tank. Possibly the overflow hose from the filler neck? Once replaced the fumes abated. Happy neighbor in his guards red 968.

Yes this happens to me as well. I had my mechanic look at it and said it could be a number of things and it would take awhile to track down the problem. He said it wasn't anything critical and to just only fill the tank half-way and keep him posted. The raw fuel smell goes away within 15 minutes of putting gas in. Sometimes it doesn't do it at all.



I figured out a way to cut down on the smell. I go real easy when I first start out pumping, then I only go as high as the first notch on the handle. Sometimes I just keep it real easy, so there won't be any splash back or overflow from to much fuel being put in at once. Seems to work for now, good luck!

Here's the screenshot of the fuel line / filler hose / reservoir / clamps etc. All these little elbows, hoses, clips, etc are the suspects I would guess - any of which might be cracked, blocked, loose which could lead to leaking fuel.



I'm going to run the tank a little lower and then check for leaks, as I am still getting a raw gas smell after running 50 miles down from the refill. I suspect that fuel soaked into a foam gasket somewhere and that's the source of the smell now.

I think I will try this good advice. Welcome to the forum, Seric! <img src="/forum/images/smilies/968/smile.gif" class="smilie" alt="" />
