04 Silverado fuel line help

I need to know which line is the supply and which line is the return on an 04 1500 silverado. There are two lines on the fuel tank, one on top and one on bottom. Which one is the supply to the engine?

There is no return on '04 and up. The other line is the evap purge. So the line coming from the tank module is your feed.

Thanks a lot. I didn't think it was supposed to have a return, but didn't get far enough underneath it to see that I guess.
