Correct fuel line clamp

What is the correct fuel line clamp for the line coming off sending unit?  Crimp? Tension?

Crimp.

I believe the "crimp" - don't have a Osborn assembly handy, others will chime in...

[tonys_shelby]

Perfect. Thanks

Crimp clamp without the divet if you want to be accurate.

Typically they would not have the preformed deep "divots" or depressions  in the clamp band as seen in the pictures above on originals. Those appear to be reproduction of one of the newer versions 

Same ones used at the front of the car from solid line to fuel pump. On later cars the ones used along the driver's side frame rails are the band style





Later version at the front frame rail for others looking for additional details

[tonys_shelby]

Great. Thanks for the pictures.

To dive a little deeper into the crimp style clamp...

Don't remember where, but somewhere I've read that OE crimp clamps marked with a "C" logo we assembly line correct for 67 and earlier, and the "E" logo marked clamps 68 and later. Would like to get clarification on that.

Thanks.

To add to Jeff's comments the spring clamps at the torque box are olive drab identified 5/16 sized.

" c " marked clamp very helpful I'll have to see what I purchased. Along with the clamps the fuel line looks unmarked with "gas" in all the pictures if I need to address this would be the time. I have a one piece fuel line. And should line by tank and before pump be same, with or without "gas" markings.

Guessing this "C" and "E" relates to the line size;
5/16 = '67 and earlier and
3/8 = '68 and later

Later type 3/8''  use 590 marked

The '.590' on the clamp should indicate the size.

The hose at the tank and before the pump typically had the gas gas gas markings.

Yes, both clamps are the same size, both marked .590, so don't think it's a fuel line size thing. The "C" clamp shown above was part of an NOS C5AZ-9155-B Rotunda filter kit so should be correct for 5/16" line. Just don't remember where I read it was a 67/68 change.
