69 b body fuel line clip or clamp??

where the fuel line enters the rear wheel well and travels down to the edge of the body/frame. is it held to the wheel well by a clip or a clamp? it looks to me like a clamp (imprint in the undercoating) but the hole doesn't have threads?? a clip fits and works but seems Mickey Mouse. whats the correct way before I go buy a self taping bolt

It is a clip.

Installed on the brake line but it is the same on the fuel line on the other side.

Thanks Mike, I figured it must be since it fit and there were no threads. sadly, your second post attachment didn't post but I think I got it! i'm a whiz at 'pushin it in'! (cue Michael from 'The Office)

Look up Right stuff detailing.They sell the complete set of hardware for the fuel line from the tank to the front of the car .part#BCS011
