Which fuel connects to what?

[sethc24]

Hey guys i disconnected the fuel lines from the motor a while ago and am now in the process of putting the motor back in etc. There is a blue covered line and a Grey covered line, my question is what one connects to the line to the FPR and what one connects to the bottom of the fuel bowl?

The smaller line should connect to your FPR as it is your return.

If you can wait til morning, I can go out and look at my truck in the daylight. I have them labeled from when I took them off to do the fuel line a few months ago.

The smaller one is the return line, but they both look like they're the same size.

ah okay. I actuelly went and looked at my parents truck ( 01 7.3). And figured it out.
