I think the breaker might be the easiest route Rick. The grommet was gone on the left side of the 4.5 too, to preserve the line as best I could I used a small piece of old radiator hose and fitted a rubber wrap. I think the clamp is secured to the block with a 5mm allen. It was a pain to fit the rubbar and the line through there, but now the line is protected, at least for a little while.
