Injector line clamps?

[Dustyman]

I redid my return lines and had to replace #8 line because of a hood/cowl molding being all messed up and letting water drip on injector. So anyway.... I noticed there were spots on the original lines that there were obviously clamps at one time, and all of mine are gone. Is this a problem I should worry about?

Yes, the lines will crack eventually without the clamps. Im sure someone around here knows where to get them.
