Possible, but not likely, although you could have the wrong banjo bolt.
To check remove the copper washers, then reinstall the block and the bolt only finger tight. Is the block then tight or loose, in other words, has the bolt clamped it tight?
If so the you have the right one, and can reinstall the washers. If it is loose then you have a bolt that is to long, or a block that is to thin.
