The forum search program is not very good. Use the google search with autoacforum checked and you'll find older posts.

"Snug the clamp up, then warm the fitting with a hair dryer or heat gun. 150f is good, do not overheat. While the hose & fitting are still hot, tighten the clamp".

Is there a torque setting for the locating arm worm clamps ?

Covette:

No apology necessary, I was just refering to how uncommon this has become. Glad to help.

The worm clamps probably have a torque number, but I don't know where you would find it - perhaps an old (1965?) Motor manual at the local Library?

You could practice with a piece of hose & a fitting using a new worm clamp without the locator. Crank one up with a beam type torque wrench until it strips. Then back off about 20%
