Leaking gas.. help! "which line?"

[dirtbike@warwick.net (Dan Kraus)]

Hello everyone,

While my car is running it will drip gas from one of the two gas lines.  IT
LEAKS WHERE IT BENDS UP INTO THE MOTOR COMPARTMENT!
Problem: I don't know which line is leaking though! If gas drips out while
the car is running it has to be the feed line CORRECT? No gas goes through
the return line while running right?

Thanks,
Dan Kraus :-)
