Fuel smell in cabin

[wckrause]

When the car has sat overnight with the windows up, I get a mild fuel smell in the cabin. Do the fuel lines run through the tunnel, and can they be inspected very easily? Are there any fittings in the cabin area that can be inspected?

I'm going to let it sit overnight with the front hood up to see if the smell might be coming from a leak up front. Anyother suggestions?

Had the same problem with my 86' 911 cab whenever I filled the tank. Check the braided hose in the trunk on top of the gas tank. Mine had a small leak in it. Replaced the hose, no more stinky cabin!

It does seem to be strongest just after filling the tank. I'll take a closer look up front. Thanks

I have an 85 and I do know that the fuel lines run through the tunnel. How do I know? When I had my seat rails lowered, so I could fit with a helmet, the guy who was welding heated up the tunnel a little too much and melted the fuel line. Not a fun fix.

Check the sending untit gasket in the top of the tank. Check the fuel return lines in the trunk area. Chech the big fuel filler hose. Small leaks make big smells. Good luck!

Check the clear vinyl vent hoses in the trunk, under the carpet ... with age they shrink and can pop off the friction-fit barbs at the junctions!

Several years ago I had the same problem of a fuel smell inside my p-car. I don't remeber where I read this fix, but I tried it and it solved the problem. Replace your gas cap. This is a common problem on 911's. Sounds to simple to be be true, but it worked for me.

I pulled the trunk carpet out and checked all of the vent lines. There was a little bit of discoloration around the vent connection to the top of the tank. I drove the car to the gas station, placed paper towels underneath the filler hose and all of the vent lines. I then topped the tank off really full, and drove home. None of the paper towels showed any sign of a fuel leak, and there was no smell in the trunk either. I'm letting it sit overnight with the trunk open, but the cabin closed up to see if I still get the gas smell.

Warren -- The vent hoses weren't clear vinyl, but braided with hose clamps.

There don't seem to be any leaks from the fuel filler or vent hoses. I'll take the skid plate off and take a look at the lines around the fuel pump. Anything to look for in this area????

I had a leak under that skid plate. Mine was on the hose that went from the pump into the tunnel. The leak was at the tunnel side fitting. Had to Dremmel the old fitting off, made diaganol cuts across it. There are several connections under there including a return line from the tunnel to the tank and a line from the tank to the pump.

Good luck

Hey Bill!

My problem was the braided hose. It was a little "Pinched" going under the main gas fill line. I had to squeeze mine a little to find the little drip of gas that came out. Good Luck!
