2007 Peterbilt 379 Fuel Lines

[Bulljammer]

Well the hits just keep on coming! All my fuel lines from the tanks to the engine are old and brittle, I noticed fuel dripping on the exhaust pipe this morning. Peterbilt tells me their are six lines of all different diameters and it's important to keep the lines equal length to keep the tanks equalized. So I'm off to the house to replace the lines.

Anything I need to be aware of or is it pretty straight forward?

Do the lines need to be primed or will the system reprime itself?
