My dad and I are just about to get my 04 aveo running. The fuel line puppoed off and snapped the clip. We were looking at solutions to get it running asap (I need it for work), and he didn't really want to order another fuel line because of shipping. So he went to Advanced Auto Parts, and found an assortment pack of Fuel line clips 5/16", 3/8" for FORD. Made by a company called "Needa?" Product number 800-023.
Snapped right in, and fit PERFECTLY. With 5 others for fixing just in case.
Don't wire tie your fuel line.... this is a cheap $4 fix.
Thought i'd share the cheap find! Good luck, guys!
