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...
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

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.
Are these .590 C clamp's available from Vendors?
And used to attach the short rubber section right at carb on 289 Hipo?
I think Randy is asking about '67 GT350 HiPo, 4-spd. See two versions that are seen out there...(will try and add images)
Squeeze/spring clamp or crimp clamp

The originals crimp clamps are getting very hard to find . There are generic substitutes that look the part identical (no dimples)except for the markings . The same goes for the spring clamps. There is historical picture documentation for the spring clamps . There is only anecdotal evidence for the crimp clamps being used there although they are used at carburetor fuel filters in other applications. I would suggest using the springs clamps at the filter especially since you have a early car which the historical picture is of a early car so we know in at least the early car case the spring clamp is most likely the typical.
Thanks Bob,
I agree too about using the spring clamps, the photo that I think your referring to does show them quite clearly, thanks always guys!
