Clamp to what?
The Teflon hose uses special AN fittings with a ferrule much like is used in copper tube compression fittings.
I doubt it could be effectively clamped like the rubber lined hose can.
That said, with the pressures we run in the FI systems, you should be using the proper fittings.

Teflon is insisted on by most world motorsport bodies where fuel line runs inside the cabin. And Teflon is essential to prevent fuel smell inside the cabin again where routing is inside.
Plus Teflon is safe for all fuel types. Nitrile rubber is not.
But it should also be used with the correct fittings. Clamping this style of hose is not the correct way although in some cases it might just work. Obviously any pressure ratings would be very low with a clamped hose.

Companies like Earls have specific re-enforced hydraulic hose for PAS lines and steel fittings, even they do not recommend normal Teflon or even alloy fittings.
That said, A friend even used a normal brass compression fitting on a steel PAS hardline and it never gave any trouble many years on. That is rated nowhere near 3 figures either !
I know on my own car I used their proper PAS lines. Why risk it when PAS is extremely flammable, and Ive seen a few cars go up in smoke because of dodgy PAS lines.
And as Sarg says, try not to mix and match across different brands. There can be small differences in sizing, and that's all that is needed for a leak.

Are you talking about clamps to attach it to your frame rails?
If you are something like these would work.

Also when you use braided stainless like make sure you keep it well clear of any other lines, hoses, or wires. Vibrations can cause it to cut thru or other wise damage them.
Good luck

What brand did you buy? If you know contact the manufacturer for guidance. I you are not sure go to several different manufacturers web site and see what is available. Teflon fuel lines are better than rubber, methanol is very corrosive to rubber products. Almost all fuel these days has methanol in it. The Teflon will last as long as you own the car.
Manufacturers;
Goodridge
Fragola
Russell
Aeroquip
There might be more but that's all I can think of right know.
