HELP! dark gasoline leak

So, I have just got back to the country and I had been planning on bringing my Rivie back to life. It was having stalling problems, so I started by replacing fuel pump and filter, plus spark plugs and wires. But now it started to leak from somewhere under the engine right in between the two front tires (I will post a video in a bit). Any ideas what could this be? the leak is pretty constant, but only happens after I start the car - any help would be hugely appreciated, thanks!

Here's the link to the video of the fuel leak

Open the hood and take a look at the fuel lines. They are up top so they are easy to see. If the leak is not there, then it is under the car. You should be able to find the leak if you lift the car on jack stands and crawl under there. Run the car just long enough to confirm the leak.

Won't take long to find that leak. You might want to buy a pair of ramps (convenience) and you might want to be (mentally) prepared to replace a bunch of metal fuel line, starting back near the filter/tank.

I do not think it's the fuel lines because this only happens when I start the car and if the leak happened before the fuel enters the engine - it should also leak when you simply turn the key without cranking the engine...

anyway before I tow it to the nearest repair shop, where nobody has any idea how to fix buicks...(because I am in the far East of Europe, country Georgia) Could you give me your thoughts on this:

I have been doing a little research and found out that when Fuel Pressure Regulator goes bad it can send fuel to the vacuum and ultimately you would have a stalling engine with fuel running through your exhaust - and this car does stall terribly; and if the exhaust pipe has a hole - it could be dripping from there, couldnt it?

I just wanted to get extra opinions on whether FPR could cause such a leak, because that is the only part I can think of that I have not yet replaced in the fuel system which would explain the stalling as well; Please let me know what you think, before I tow it to some mechanic that has never seen this engine before...

P.S. the three fuel lines look nice and dry when you pop the hood, I have not yet looked at them from underneath because I wanted to make sure it wasn't the FPR before I tow it somewhere

At some point, you'll do what he said... just sayin'... by the way make sure you're not mistaking air conditioning condensate for fuel.  I doubt you did but rarely it happens.
