Help! Which plastic pipe to fuel regulator is "in"

[Noblehops]

So close, but the bike won't start, the fuel pump sounds funny, and the plugs are dry. I think I may have reversed the fuel lines when I installed the QDs.

Which of the two black plastic pipes to the fuel regulator is the input? Once I know that I can find out in 2 sec if I'm right, and ust swap teh QDs, but I'll be dipped if I can find it in the Clymers or factory manuals.

Help ASAP! I'm so close!

The upper plastic hose is the regulated return

I've gotten in the habit of taking lots of pictures during tear-down because if this kind of thing.

This picture shows the Fuel Tank laying on its side on the RH Cylinder (rag underneath).


This picture shows the Fuel Lines and you can see the upper one is the shorter of the two.

Thank you kindly, both of you. I did mark the upper hose and noted that the upper on the tank went to the upper pipe, and that was actually how I had it. So that was not the problem.

The problem was that the QD on the lower (which I now know to be the fuel supply) was 1/8" from clicked, and so no flow. Once I stripped the plastic and fiddled with it I found it, clicked it home, and lo and behold, it fired right up, and after clearing it's throat for a few minutes, it ran fine! Awesome!

So I went for a ride! And it quit - but then it restarted! And the low fuel light was on because I had so little fuel in it, so I took it to a gas station and it took 3.66 gallons, and then fired right up. So I thought - "Perhaps I just ran out of gas". So I took it out to the highway for a bit of an Italian tuneup. And it ran fine! Until it quit, but I was able to glide off my exit, and push it for a short distance, glide it down the hill to my friendly neighborhood gas station, and I just fetched it with my trailer.

The fuel pump is silent now when I turn the key.

When I was troubleshooting it before I realized the QD was not connected, it was making a rather growly, gravelly noise. Not like the machine-ey sound my GS fuel pump makes.

So:

Given that I cranked it with the QD shut for 2-3 minutes off and on, could that be the coup de grace on a fuel pump with 57K miles? As I say, it's dead silent wen I turn the key - I haven't put it on the GS911 to see if it's reporting a fault yet, but I will. Could it be a fuse?

Advice welcome. I am annoyed at myself and a little discouraged right now.

I'd make sure the Electrical Connector terminals to the Fuel Tank are not corroded - they tend to get that way after some time/miles.
