Nothing keeps the line from popping off when it is weak. You would have to
use some sort of clamp or wire. I think however that this is an emergency
patch job which may be needed in a pinch. A new proper size fuel line will
fit snug and it would be unlikely to pop off.

So the oil and fuel has no bearing; in your thoughts.

You will not get good best result without a clamp or wire.

Would the line stay on for a few minutes, maybe!

The OP wants to stop it from popping off. (I cannot tell from here if
he is fifty feet up a tree, if so we send him up another saw).

The snug fit won't last.
