Fuel Leak

Noticed fuel leaking right under the passenger rear door. It is a drop every 20 seconds or so. I am pretty sure the leak is coming from the line from the tank to the engine or wherever. Not sure how many lines there are...
Additionally, what would the difficulty run for a "DIY" kind of person?

Sorry to say, but if you have not ALREADY found your very dangerous fuel leak, and fixed it...you should not be attempting to fix it, and should not be driving your car. Some vehicle repairs are critical Safety Issues, not to be attempted by the DIY/amateur; this is one of them. Make an appointment at a NEAR-by repair shop, and either have your car towed there, or drive it DIRECT-ly to the shop, calling ahead to alert them that you are coming in with an active fuel leak(!). You should have a large fire extinguisher with you in the vehicle that is Rated to put out Gasoline fires...and do not smoke while driving there, and do not let any other customers smoke near your vehicle when at the repair shop!

Put the car on jack stands and verify what and where it is leaking. I am not sure on the 92-99, but the 2k and 89, the fuel lines run down the driver's side.

92-99 the lines come off the top of the gas tank and run down the rear frame rail and them along the passenger side of the car.
I can't say for sure what is leaking on your car but on our 1994, the lines were actually leaking where the metal line attached to the plastic gas line because the rubber connector had rotted away. (You be lucky if thats all it was). Some tranny hose and a few connectors and it was "fixed." Only to find that the metal line up my the gas tank was so rusty, it too was leaking.
Take a peak at the lines, but don't be surprised if you end up dropping the tank.
That's why I've held off on ever changing the fuel filter on my 1997, in fear of breaking these gas lines.

Very simple, crawl under the car and look. Its either the gas tank itself or one of the lines.

Yep, fuel filter is right in that area near the front and rear passenger side as well, it's probably leaking somewhere in between the line that runs from the tank to the filter.

If you need to replace a section of the nylon line, you can get a repair kit and separately find these:

8mm
10mm
Of course, use a calipers to measure the OD of the line, to verify if you have metric or SAE. I didn't, and found out mine were metric.

So it can be done... Was worried about the $500 shop charge (about half of what the car is worth).
So many responses. Good news is that it IS between the tank to the filter. I too was scared of changing the fuel filter about 10,000 miles ago and will probably hold off for the fear of creating problems.

I'd say since you got a leak anyways and will have to replace a line, go ahead and change out that filter since if anything is gunna break, might as well have it happen when you have to replace parts anyways. And fuel lines are something a diy'er can do themselves, just as long as you use the right parts and tools for the job

The high pressure line from the fuel sending unit quick connect to the filter can be very stubborn to release from the sending unit end and often breaks in the process. The line is one of the few you may find stocked at your local dealer.

I agree with motopsyco - change the FF and see what line is leaking , probably anound the FF connections .right under the passenger door is the fuel filter

Yep the line is patchable. I had a critter chew through mine in the same area. Patched it with the fuel line patch kit from carquest. No problems after four years.

Several members in the past (myself included on my 95 SSEi) have had this leak. More often than not you're looking at having to replace the entire fuel tank sending unit. The steel lines like to rot out and the leaked fuel trickles down the line and hits the ground right behind the fuel filter. The order of fuel flow:
Tank --> Pump --> Sending Unit & Steel Lines --> Quick disconnect/Nylon Line/Quick disconnect --> Fuel filter
I used double-clamped rubber hose in lieu of replacing the nylon line, because I mangled the quick disconnects upon removal. You will have to drop the tank to do this.

Sounds exactly like the issue i have. The leak is coming from the line but more up towards the tank and the fuel trickles down the line and drips where the line bends before the fuel filter.

You can contort a bit and look at the upper quick disconnect on the nylon line. If you can determine that this or the nylon line isn't leaking, you probably need to drop the tank and swap out the sending unit. It'll look like this:
