Its the mother****ing **** ****ing gas tank. The rear edge of the tank, the part closest to the rear sway bar, is just dripping with fuel. There are no openings/lines exiting the tank on the outside, correct? If it is leaking like this, it can only be the fuel tank, right?
If I do need to replace it, should I upgrade to a Walbro or whatever fuel pump while I'm at it? Having the extra pumping capacity will not change my fuel economy if my mods/driving habits remain the same, right?

its probably 1 of the 2 rubber lines that go to the top of the tank/access cover
we had this issue on our ser, it was leaking fuel like a big dog

I do not get any fuel fumes inside the car with the windows closed. Are these lines connected to the tank outside of the car (not under the back seat?)

does your tank hold pressure? does it hiss when you undo your gas cap?

There could be a chance that the gas smell that you are talking about can be exhaust fumes they have a similar pungent smell to it. Check all your joints from the head back. Also check for cracked haeders which I think I have.

I had filled up on gas last night and parked uphill, which I think made things worse. After wasting some gas and parking downhill, I took some pics of where it was leaking:







And here's how much it leaked overnight:



Could it still be the lines under the backseat, or does this look to be a problem with the tank itself?

Check the breather lines. (The ones that go from the tank to the feedneck) I had i similar problem. It would leak when it had a full tank till it got to half tank.

thats exactly what ours did, replace both the rubber lines under the back seat, MAKE SURE you use hose made for fuel injection!
