Are you sure it's fuel? I would guess oil or PS fluid.

Yeah I'm sure. It drips at a pretty constant rate and has a strong odor of fuel

Most of the fuel lines are hard lines, which are unlikely to leak like that unless damaged or badly corroded. Up in the engine bay is where it's mostly soft lines, so you'll want to feel along those for moisture.

The fuel pressure regulator is my best guess at where the leak would be. If new copper crush washers weren't used when the PO did maintenance work, that could definitely do it.
