Hello, there is a revised line made available, with a different mounting, as this line did have breakage issues. I would get a new replacement line, new banjo bolts, and seals. This should repair the issue. I say new bolts, because they have a tendency to stretch, crack, and leak. When you install the bolts, snug them tight, but do not over tighten, as they stretch easily. Since the line goes from the pump, to the block, then the oil filter housing, the pump mounting should be checked. Make sure the bracket at the front of the pump, on the bottom, is in place, and tight, as it will crack the line if it is loose, or missing. Good luck...Gary
