Now it is spraying again after replacing the line clips...moved the line a tad I guess and rocked the line head at the injector mating surface? Lines don't seem to be leaking unless it is the cone shaped fixture joint fitted to the injector side of the hard line.

Can I reset the surfaces (injector inlet & hardline cone shaped end) with some valve grinding compound or something.

Or do I need both new injector and new line?

Thanks

Just in case your thinking "return line" that's not it
