Okay, I managed to find another line that was hidden down around the transmission. It has a 90 degree elbow, like the one in your pic. However, there was already another line with a 90 degree elbow coming from the driver's side. I'm guessing one is the red or yellow line in your pic. Since all of mine are 90's, let me describe where they go and make sure I have it right.
First, one goes behind the brake cylinder and ends up at a device next to the clutch fluid reservoir. For those with automatics, it's at the back of the firewall on the fender behind the shock tower. I'm guessing this one goes to the blower bypass. The second one goes behind the brake cylinder also, but I can't tell where it ends up because it goes behind other lines. I'm guessing it goes into the firewall. This must be either the red or yellow line, whichever the fuel pressure regulator line doesn't reach. And then the FPR is the third. If I can just verify where the first line goes to, I should be able to figure out the others.
Thanks for the help. I should learn to label these lines, though after this, I'll probably have them memorized.
