Fuel Lines Question

[BlackLX5.0]

The two fuel lines that come off the top of the intake runs down the passenger side to the frame, which ones the main fuel line and the bypass line? Someone told me I have to know which ones which before I hook them up.

Thanks

the feed line is the bigger one. if you are following the lines back to the fuel rail, then the one that goes to the front corner of the rail is the feed.
