I love the smell of gasoline in the morning

I woke up in bed smelling gas. I walked downstairs, it was stronger. Hmmm....

I walk to the garage, there is the car, and there is the HUGE puddle of gas under the tank. What the HELL happened? Dammit dammit dammit. I am now donning my pseudo-mechanic jumpsuit and going out there with the jack and the camera to investigate. You can be sure this will turn into some type of ridiculous saga that requires the assistance of hundreds of 944 owners all across the country. Everyone get ready, its gonna be a party tonight. Woo-hoo.

Loose clamp? Don't take pictures till you have ventilated the garage well! No sparkey, no lights, or go BOOM!

I probably won't have pictures till tonight now, cause it seems I left the camera in the woman's car.

So... I jacked it up and took a look under there.
Observations-

1) Once I jacked up the right side, the leaking stopped.
2) No gas anywhere near the fuel filter or the junk going to and from it.
3) No gas coming from the spot where the hose thingy goes into the tank.
4) There is a cover thing that is foam backed and it goes across the entire bottom of the tank. It seems to ME like the gas is coming from somewhere under there. All the foam stuff is totally soaked with gas. Can I remove this and check for stuff?

Is it possible that the tank has a hole or something?!? I was really hoping I had screwed un something with the fuel filter, but like I said that area is bone dry, as are all of the hoses, as far as I can tell.

sorry to say, but replacing the tank isn't fun. Removing that requires removing the transaxle and possibly the torque tube.

One other interesting note- I was almost out of gas, and when I filled it up 2 days ago, I smelled gas for awhile. What the hell am I supposed to do?

I had a very similar problem a few years ago. Turned out to be a worn hose near the fuel filter. While changing it out, I experienced a new definition of pain as a drop of gasoline hit my eyeball. Luckily, this car was designed with the gas tank OPPOSITE of the exhaust. Otherwise, we'd have problems.

So I decided to lower the car back down (I had jacked up the right side) and see if the leak would start again, and boy did it ever. Gas poured out for like 2 minutes. Now its like a trickle again. I sill can't tell where it is originating. It seems to be all exiting at one point, it looks like its leaking from under that secondary plate thingy, and under that metal strap thingy. The hoses are still all dry to the touch, at least the ones I know about. I really need to get pics for this. Keep the advice coming... cause now I NEED the car for work, so I don't have the luxury of time.

My only words of wisdom borrowed from my TR-6 experience is to make sure you don't mistake a low point (of a leak) from the actual source. But you probably knew that already. Get a buddy to jack the car up/down a bit while you take a flashlight and probe for the source of the leak. Just be VERY careful that the drops don't come anywhere near the light. Automotive gasoline has a nasty habit of igniting just by looking at it the wrong way........

Good point. Considering that I noticed the smell after having the tank filled two days ago, that would support the leak being at a higher point. Also, the leak stopping when I jack the car from the right would support the leak being on the upper righthand portion of the tank. So I need to look at diagrams and figure out what is up there.

I'm concerned about burning up too. I set up a box fan to keep the garage well ventilated, and I left the garage door open as well. I am keeping my light as far away as possible. I will be stopping for now until I get my camera later this evening to get a diagnosis from yall. Unfortunately, I am sensing a large mechanic bill in the near future, as I don't know if this will exceed my decidedly limited capabilities.

I'm also looking through the PET diagrams to get an idea of what to look for. If anyone wants to describe some stuff to be in terms of PET part #s you would rock. Oooh. yeah.

Fuel filler line might have cracked. That happened on my brothers Range Rover a few weeks ago. Pain in the ear to fix. Literaly. I got a stream of gas that ran down my arm and into my ear (I was laying on my side). That hurt worse than when I ripped a toe nail out (whole 'nuther story).

If you're not joking, then no, I don't have enough space for all that gas. I just filled it! If you are joking, stop tricking me!

Should I accept defeat and go to the shop?

last week when i took out the fuel sending unit to clean all the connections i noticed that the tank was almost full at that point and i only had half a tank full. i would check the gaket on the sending unit...lifting the right side of the tank would certainly move the gas over and away from the sending unit.

Please tell us that your gas water heater or furnace is not anywhere out there. Boston is not known for gas heaters, I know, but you'd be surprised at the things that make sparks. Even fans like the one you are using.

No furnace anywhere nearby . I figure its gotta be pretty safe, having the door wide open and all.

So about this sending unit- what is the part number for it? I am trying to locate it on the diagrams and I haven't found anything yet. Also, how the heck do I get at all of these things? It seems like they are all at the top of the gas tank or inside of it, do I need to remove the tank to even investigate?

update

So I got bold. I unscrewed the strap thing that goes around the tank. This allowed me to peek under the black plastic under-cover thingy and verify that:

1) The leak is from somewhere under there.
2) There is a canister thingy under the plastic cover with some hoses.

I'm gonna dry things up in there and try to pinpoint the exact source of the leak. If this information is enlightening to anyone, let me know. Sorry for being cranky-
