Welcome to Just Answer, I will do my best to help you solve your problem
You can't repair this without cutting out and replacing the fitting. This line is constantly under pressure.
Anything else will not be a permanent fix
Is there a "temporary" fix you could recommend?
the only temporary fix that might work is to wrap the pipe with rubber gasket material then use a hose clamp or clamps over the gasket material and tighten down the clamps. This works well if the leak is in the middle of the pipe, it's not as effective on a leak at a joint
OK ... Thanks.
