Fuel Line Question

Okay Guys ,
Question , i know i can check fuel pressure thru my gauge but i want to SEE the actual fuel being pumped out , which line will the fuel come out of?
The one that goes to the regulator or the one with the pressure valve???

If you just want to see fuel coming out then disconnect the supply line (one with valve on it ) ) to rail

Only on '85-'88, the later cars had the same size lines on both sides.
