Fuel leaking, but from where?
I'm trying to locate the source of a significant leak without removing the fuel tank.
The leak began a couple days ago and has progressively worsened. The tank was replaced in 2007, so I'm thinking it's a ruptured line; however, the high pressure and return lines are on the passenger side, and there's only an EVAP line on the driver side.
Could fuel be leaking and pooling somewhere such as the spare tire carrier, and then flowing to numerous places before it spills to the ground?
Here's a brief video:

Holy crap. You better find the source of that quick before you play a part in the Towering Inferno. Drop the spare tire carrier and you should be able to see if the tank is leaking and where. These tanks have a rubber liner which is pretty tough. If your lucky, it might be one of the fuel lines, but that is leak is pretty big for a bad line. Good luck.

Those vapor/EVAP hoses (runing down the drivers side) rot out and cruble over time but usually you can only smell the fuel vapors. Pull the "fuel fill" door panel & overflow catch boot and take a look between the top of the tank and the body panel while repeating the same situation/conditions as before.

Thanks for the responses. I'm usually hands-on first, then report my findings second. This is someone else's (aka "Narnian") car that I'm keeping for a while and, in exchange, repairing.
The fuel hoses are both wet at the fittings on the passenger-side in front of the fuel tank area. The car runs fine, which is why I suspect a ruptured return line. However, until this weekend I can't get the tools and facility to work on the car, so I posted here hopeful someone would chime in before I dive in. Thanks.
If it's a ruptured return line, is why might it be spilling around the spare tire carrier?

The fuel door is held on by just torque screws and if not to tight you may be able to get them out with a simple screwdriver. Pop the license plate off for better access and your there. Unless of course you have nothing to work with at all. Then you can get a look at it.

You've got some good advice...take the fuel door off, pull the boot out, wash that area down and LOOK for the leak before it drips on the hot exhaust and ends your day.

I don't know if this will help you or not, but JeffVette has some great photos of the gas tank without the rear bumper on. It might help you visualize what's going on under there.
